Not bad for a Monday. 63.6mpg on the tank at ~50mi.

On the colder side of spring this morning, and I was behind a slow van so I couldn't lock up the TCC and my uphill FE suffered accordingly. Segments of 36/40/48 MPG for 41.1 MPG at 42°F for 15.4 miles.

I just got it in my head to sticky the week's active thread so as to keep it at the top. Other mods feel free to un-stick it if you think that's pointless.

Hi Tim:

___Sounds good as long as we remember to unstuck it first thing on the following Monday. I just replied to last weeks thread not thinking it really is Monday ;)

___56 - 60 degree temps with winds picking up the further I traveled south. Fortunately, the really strong stuff arrived only in the last 10 miles. 5 - 20 + mph headwinds on the way in this morning. 54.0 into the lot. This afternoon, it will be in the 90’s with that same wind only from the rear. 960 miles out and low fuel just lit up. 1080 + should result. My fingers are crossed anyway :)

___Good Luck

Interesting morning.

88.1mpg at 65F.

Starting out, a couple of slow moving vehicles almost were in the way (when you are going slower than a hypermiler - you are too slow)

Once on the freeway, a couple of pickups did the "pass on the shoulder/exit ramp" number :mad: :rolleyes: Interestingly, the electronic sign read: "Buckle up Trucks".

Finally, I glided 0.2 miles to the parking lot, rolling thru a green light. Was going to let gravity let me back in, but someone was in the way - turned out to be someone come in early and had to crank the engine.

Good drive in. 53mpg. Dont think the evening drive will be near as good. Suppose to be a head wind of 15 to 20 mph. :(

I beat the wind by the hair of my chinny chin chin today. With a brisk headwind coming home I was able to get 50mpg.

psy

managed to hold it at 60.5, both MPG and MPG in spite of a strong head wind. the bumper clippers were out in force.....you know, the ones who come roaring up behind you and whip around as close as they can to pass.

must be because i stuck my tasteful new european bumper sticker that reads 60MPG on the driver's side bumper on the back......and they are feeling the pain of their 12MPG.....oh well, a girl can dream.

53.6 this morning.
Tank at 51.0 / 268 miles. Looks like a 50 fillup is possible...

First commute to work since installing ScanGauge - tried a slightly different route just for grins and giggles - and pulled a 32.1 mpg for 10.5 miles on the ScanGauge :Banane04:
I did forget to check the regular odometer before I started, but I think the route I took is normally about 11.5 miles, will check it tomorrow. I have approximately 4 routes I can take to work, now the fun begins to see which one really gives me the best mpg. This route is mostly suburban main streets, with a short stint on Route 83, but seems to have some convenient hills for N-ICE or FAS.
Did I mention I really am liking this ScanGauge? ;)
I actually haven't posted any questions yet in the ScanGauge forum cuz I kinda figured the answers out myself so far.

Good job, SlowHands! Start working the pulse and glide when you get a chance -- that's where my mileage really shot up after getting the scangauge. I started getting segments in the high 40's just one week after getting the device. :)

Wayne -- thanks for the encouragement! I'm pretty excited about the extended range and better efficiency I'm seeing now but still nervous about running out of fuel. I think I might just pick up a gas can and go for the distance. Now that I can get anywhere in the Twin Cities on just one gallon that's all I need to carry to be safe. ;)

Finally able to watch the psyshack & highwater news item. Great job fellas.

108 to work, and ready for another go at an 80.0 TODAY. I'm hoping to keep the tank as close to 80 as I can for the next 10 days, before I head off for another highway trip.

59mpg this weekend downhill to the coast @ 55-60mph on state highways. 55mpg back uphill @ 60-65 on the interstate. Now, I expected to get passed doing 60-65 on the interstate. I expected to get passed A LOT. But I did not expect to get passed a lot standing still. Since when did the interstates become the autostrada? The average speed of cars that passed me was in the neighborhood of 80.

Well I finally filled up for the first time in a month. Completed my tank at 41mpg, no where near my record 47mpg but that's because this tank was almost all hwy miles.
I got 43mpg for 50miles out to my RC flying field, and then I was dissapointed to see headwinds were picking up for the trip back but I finally lucked out!!!

For the first time I got someone going slow enough for me to draft behind. A Ford Aerostar Van pulling a 6X10 enclosed trailer. It was perfect and he didn't mind having me back there the entire 50mile trip back! I got 48mpg at 55mph letting him fight the 20mph head winds with 30mph gusts for me. :Banane05:

I sure like my new ScanGauge...Trip home was near mirror-image 32.0 mpg of this morning's drive to work, even with strong side winds. Did I mention I like my new ScanGauge?
Oh by the way, took the Bronco to the gas station this afternoon... WTF gas jumped from 3.229 to 3.499 from this morning :mad: :mad:

Finally able to watch the psyshack & highwater news item. Great job fellas.
Agreed!

A pretty good day today, despite yet another sub-40F May morning. 64.5 MPG on the a.m. commute from my fiancee's house, 39F. 76.0 MPG on the p.m. commute. Tank's at 72.9 MPG at exactly 600 miles, 1 pip left.

Keep up the good work, SlowHands!!

Well, I've decided to tempt fate and keep going on this tank even though my gut is screaming that I'm insane for trying it. I'll put the gas can in my car tomorrow so if I do run out I can just pull over and dump a little more in so I can get to Costco for a fill.

Guys, I don't know what has gotten into me but on the way home I got the current trip mpg up to a ridiculous 58.9mpg!!!! :eek:

By the time I stopped at the post office it had dropped a bit but I still managed a personal best trip! The trip from there to the house wasn't bad either. :D

1) 55.1mpg for 30.4mi (Work to post office)
2) 50.5mpg for 6.4mi (Post office to home)

It is currently 86F, I'm sitting at 574.2 miles on the tank, and the tank average according to the scangauge is 46.5mpg. Here's hoping I can finish the tank at the gas station instead of on the side of the road and that I can keep up the good numbers! Either way, I think unless something goes terribly wrong I'll have traveled over 600 miles on this tank. :D

Nice work Sean! Still think 60's and 70's are out of reach?:)

Temps started out at 50F this morning and got up to 84F. Winds were from the south at 15-20 mph and got a bit stronger as the day went on as can be seen by my segments.
1) 53.6-5.8 miles(to wife's work)
2) 53.8-9.6(to my work)
3) 67.7-9.6(back to wife's work)
4) 61.3-6.3(home)
5) 64.6-8.3(to auto parts store in town)
6) 55.5-8.3(home)
Average for today: 57.1

Hi All:

___Great tanks by all. I was just speaking to a “Wired” writer about some of you and I hope he uses your achievements as a hook for a story about the “Best Of” story (hypermiling being one of those Best Ofs ;)) he is currently working on.

___15 -20 mph side/tail winds with 86 - 88 degree F temps. 7 miles of stop and crawls but a touch better then last week. Only 2:50 minutes to get home tonight and 60.9 showing into the drive. 1061 miles and still 46 showing for range. She has a shot for a personal best of 1,105 miles but there were way too many days of horrible traffic and conditions working against her for that to possibly happen. At least whatever she allows will be on camera for the Global Warming documentary film crew if they want to use it :)

___Good Luck

___Wayne

Jim, it was that cold in Richmond this morning? Wow!

I'm outside Philly this week for business. I'm in a rental Mazda 6 sedan. I forgot to get the ScanGuage out of the Prius before I left, so I don't really know how I'm doing. I'm guessing not well. I have to concentrate on what roads I need to be on, etc. I figure with all of the gas that I've saved since December, I can afford a week of "normal" driving. Although, I did do a little FASing tonight after dinner.

51.2 this morning
52.5 day travel for work purposes
43.6 this evening. 27017G22KT So a big upwind/crosswind.

I just can't beleve you all when you're saying you get 60mpg+ with a upwind. To get a 50mpg I should drive at 31mph and again I'am not sure I would get it.

PM

Good job, SlowHands! Start working the pulse and glide when you get a chance -- that's where my mileage really shot up after getting the scangauge. I started getting segments in the high 40's just one week after getting the device. :)

hey, welcome fellow minnesotan! i am north of little falls.

Larry, it is starting to look like 60+ might be in the cards for just the right circumstances but I'd be very surprised if I managed 70+!! Most of my driving has a significant percentage of highway mileage... though I am starting to get the hang of ramping it up substantially whenever I have to slow down significantly, and then doing a passable job of maintaining it during the faster segments.

Hello, Laurie! North of Little Falls? So you are at least 90 miles north of me -- add another 25 to get to where I work (Minnetonka) so I guess a lunch time demo of hybrid driving is out of the question, huh? Too bad.

I'm actually a transplant to the area (been here 7 years this July 7th) but my wife loves me anyway. ;)

Thanks for the comments Right Lane Cruiser - looks like you're doing pretty well yourself!
I've been to Minnesota in a former life as a travelling techie, once during a blizzard in Feb, and a few times in spring and summer and winter... seemed to have missed fall, heard the colors are pretty.
Trip in tonight to work got a 30.5 on same route as both other trips today, but seemed like I was fighting wind a lot - tried to do some pulse and glide where traffic allowed, and I think it helped to get the mpg I did. Was still a bit askeered of FAS to a full stop, watching voltage, getting a bit more confident of what will still kick the starter over. I'm pretty sure I'd be good down to 11 volts, so I've just been a woos since the lowest I've seen so far is 11.9

A new PR this morning...segments of 40/40/53.2 MPG for 15.4 miles at 46.2 MPG, 57°F with a mild side/tail wind. Oh so close to that elusive elite segment.

A Range Rover tailgated me when I turned onto my first main road, then turned to take a shortcut down a slower road, wound up behind me at its next intersection with my route, then passed in the right turn lane. :mad: I suppose it's just as well, since it left the road ahead clear for me. :)

Tank's at 557 SG miles (567 actual -- a new PR as well) for 44.3 MPG with 0.7 gallons remaining. I'll fill up after work. On this tank, I've traveled from Long Island to MA with the AC, up to Meredith, NH and back on back roads, a couple of side trips and a couple of commutes. Not bad.

Jim, it was that cold in Richmond this morning? Wow!
It wasn't quite that cool in civilization. 41F was the official low, I think. But it was 39 at m'lady's house.

Considerably warmer this morning, 55F. I had by far the best MPG ever on this particular commute (~12.5 miles): 82.2 MPG. Traffic was quite cooperative, and I made a small detour near the end to the ATM near the office, which afforded the opportunity for EV mode for the last half mile or so.

:o SlowHands, I'm just trying to follow in the footsteps of these other guys (and gals!!!) around here...

Since you have a MT, try "bump starting" your vehicle if you need to get going again but aren't stopped. I've found it is pretty hard to do at around 10mph, but I can pull it off down to 20mph without too much trouble. Higher speed is easier and smoother. I watched my voltage for a while but I really haven't had any trouble with restarting so I've not been worrying about it. I never had a gauge for that before and have been turning the engine off at lights for the life of the car (original battery and getting close to the 5 year mark).

Congrats on the record, Bruce! You're pulling good numbers for distance considering the size of your tank. :)

I'm working this tank for all it is worth. It was 56F on the way in to work with a bit of a headwind (5-7mph maybe?).

1) 52.3mpg for 25.4 (Home to work)

The tank is at 600.4mi (!!!) and the scangauge believes I have 1.2 gallons left, calculating my average for the tank to be 46.7mpg :woot:

I still think it is estimating high because I had the empty light on for the whole trip in and I would expect to have to put in about 14 gallons at this point. Maybe I didn't get a complete fill and didn't notice earlier because my trip averages have been pretty high?

What has everyone else's experience been with how accurate the gallons left gauge is? I've not found a way to input an offset on the ScanGaugeI as I've been reading you guys do on the ScanGaugeII...

I've been bouncing back and forth across the 62.5mpg mark, winding up at 62.9mpg this morning. All 10 pips still showing on the "guess gauge" at 90mi or so. Was tailgated all the way in by somebody in a Chevy Cavalier who, upon passing me, turned out to be sporting a set of expired tags.

In other news, operation "Accumulate miles at three times my normal rate" starts today. I'm going to be driving like a madman pretty much from now through my trip down to the Carolinas. Various family visits, a graduation 200mi away, etc. The unfortunate thing is that much of that will be highway mileage so the tanks may suffer a little. Oh well. Gotta do what's got to be done!

85mpg at 65F

52 mpg for the drive in today.

52 mpg for the drive home.

psy

Not sure what my commute this morning was. About halfway through, I was almost stopped at a light, and turned the key, and got "grrr... click. grrrr.... click...." :eek: I was able to bump-start it at 5mph, and then Scangauge told me, "connecting...".

It seems my 12V is on its way out. For several days now it's been low when I come back to start a drive. Low as in 10V or 10.5V! Thanks to the amazing Scangauge, I know the alternator's just fine, putting out 13.5+ while running. Battery is at 12.5 when I stop, and I can watch it tick down from there.

Battery recommendations? Wayne, you still liking that Optima? Which one was it, again?

Guys, I don't know what has gotten into me but on the way home I got the current trip mpg up to a ridiculous 58.9mpg!!!! :eek:

Holy ****, isn't that like 200+% EPA for you?? AWESOME!

108 to work, and ready for another go at an 80.0 TODAY. I'm hoping to keep the tank as close to 80 as I can for the next 10 days, before I head off for another highway trip.

Ho hum, another day, another 108 to work. :D

It's ironic that I broke my 12-day biking to work streak during Madison's bike to work week (http://www.bfw.org/btww/calendar.php). :o

But, even out of practice on my 7-mile to work route I was near a personal best.

84.1 / 7.0 miles / 68F

Bumped the tank up to 75.2 / 416 miles / 4 pips.

Still not breaking out much of the low 60’s though I’ve had a couple 65’s and 66’s.

Last Friday heading home I was almost at 65mpg, got off the freeway near USC which is usually pretty quiet and ran right into a horrible gridlock situation. They had commencement of all days, that day and people were either just arriving or just leaving. Nowhere to escape. Banged head on steering wheel while watching the trip-A tick tick tick down to 57.

Tank is still holding on at 61mpg. 62 today into work.

Ho hum, another day, another 108 to work. :D


107 this morning. :)

Fell short of 80.0 TODAY again yesterday. Will make another run this afternoon. Traffic is the biggest constraint.

I'm enjoying the posts from some of the newer guys. As I've refined my driving & route, I've slowly reached a point with my car where the fe improvements are more on the incremental side. This contrasts with early on in the game, when you are initially working on your techniques & you get to enjoy watching your mpg explode.

I'm seeing a lot of those "Holy S@#$!" posts from newer members, and they are awesome. Keep 'em coming!

from MParrish: This contrasts with early on in the game, when you are initially working on your techniques & you get to enjoy watching your MPG explode. :D

Well the trip this morning to downtown Chicago was one of those for me: about 17 miles expressway, about 4 city : 34.1 mpg :Banane27:

This is with a truck that we were usually getting 19-21 mpg... yeah explosion of mpg for sure!
I did do a bit of 'mid-coasting' I'll call it, about 2 lengths back about 1/2 the way in. But the way back blew chunks for sure... Chicago Crawl even on Roosevelt Road west of Laramie... only was able to get a 28.3 for the trip back.

Tomorrow will be the big trip with the 'Guzzler' - drive down to Decatur to pick up daughter and all her stuff and bring her and it all home. Being a 92 E150 conversion van, the ScanGauge won't work, but will be putting in a vacuum gauge to help with DWL. Its about 190 miles each way, and at $3.49 per gal, my wallet is going to scream.

Trip home from work:34.5mpg - now the fun part: for the day (so far) 31.6 MPG for 100 miles, tank: 29.3 MPG 228 miles :Banane27: Hey did I mention ever that I really like my new ScanGauge? LOL

Hello, Laurie! North of Little Falls? So you are at least 90 miles north of me -- add another 25 to get to where I work (Minnetonka) so I guess a lunch time demo of hybrid driving is out of the question, huh? Too bad.


darn, it is a bit far. i actually work in st. cloud, but it's still quite a drive to minnetonka. i got my hybrid because of the long commute, when the prices went up in 2005. i get rather compulsive about my summer rates, since in the winter we all take a pounding up here regardless of what we drive. i am also lucky in that i have options to take the backroads home and not get stuck in the friday night lake run on highway 10.....

welcome!

Hi All:

___Had a crew in from San Francisco doing a shoot for "Future Wheels". 58.7 mpg tank over 1101.2 miles and they caught it on tape.

___Good Luck

___Wayne

Laurie, Friday night lake run is right!!! :(

You know, I live right off of 10, and I also most weeks work 4 10hr days with Friday off. Maybe one of these Friday's I could swing up to St. Cloud during lunch? If you don't mind doing a demo, that is?

SlowHands -- you're starting to get some nice numbers there!

:o Yup, Locutus, that's where it's at for me! Now if I could just make that a regular occurrence!

Another 1.75 hours and I'll get to see if I can really trust what the scangauge is telling me I have left in the tank. :p

If I can make it to the station I'll best my previous record for distance by almost 100 miles! :D

Hey guys I'm back posting to the daily grind... so here's my weekly data dump... Posted three 70+ trips this week, so I'm pretty stoked. Thanks to Marc and Hobbit for getting my RPM a bit tighter, I was blowing the torque curve just a hair.

I may go and back fill the data dump for the weeks I missed so please excuse the data spam on closed weeks.

Laurie, Friday night lake run is right!!! :(

You know, I live right off of 10, and I also most weeks work 4 10hr days with Friday off. Maybe one of these Friday's I could swing up to St. Cloud during lunch? If you don't mind doing a demo, that is?



that might be possible. i work right off 10 on the east side of st. cloud. 'course my momma always warned me about picking up strange men? you aren't strange, are you?

:D

Marc, 108 Wow, I drop off the grind for a while and I'm wayyy behind... Now I have the EV+EBH waiting for install, so I have no excuse. I better pump up to 60psi.

Wayne, Cool to hear about Wired. If you hear from them, give them a nudge on the hybrid article they wrote this morning.. :(

Right Lane Cruser, Really nice work on the 600mi tank. Only time I passed 600, I had to give my car a gas bath :mad: As far as SG acurracy, I'm tuning it. It doesn't measure injectors so if you car fuel-cuts, SG doesn't know it. This can drift your gallons-left number a few ounces. I've also adjusted the speed setting so that the distance matches (or comes closer) with my ODO.

11011011

74.2mpg (437.5miles, 5.9gal) For this tank I drove mostly DWL at or above the speed limit. According to the SuperMID, the FE of my car is flat from 40 to 65mph and drops off slightly as I get up to 70mph, but is considerably less at lower speeds and in any of the lower gears.

Laurie, my wife tells me I'm ultra strange for this fuel economy kick I'm on... but don't believe her. ;)

Dan, I got back on what I had left so I still don't know how much the tank actually holds. Unfortunately the SG was off by an entire GALLON! :eek:

:( :( :(

I'm really hoping that the tank was just underfilled but I've adjusted the SG to what I put in today. I won't know until this tank goes dry. That means that all my numbers have been high if it wasn't. That really REALLY stinks.

The wind on the way home was terrible. I couldn't keep it above 50mpg no matter how hard I tried. Coupled with leaving later and getting into gridlock my numbers plummeted.

Temp right now is 61F.

1) 48.8mpg for 34.9mi (Work to Costco)
2) 39.7mpg for 1.8mi (Costco to home -- adjusted SG)

The SG thought I managed 46.9mpg over 635.6mi using 13.6gallons, but since I put in 14.7 to fill it my calculations come out at only 43mpg. :mad:

On the positive side this means I've probably got a 15 gallon tank instead of 14.5 and could probably stuff it to 16 if I tried.

Guess I'll live with lower numbers this tank and hope that get a pleasant surprise on the next fill and find that I was indeed low on this last tank. One can hope...

Hey guys I'm back posting to the daily grind... so here's my weekly data dump...
Hey, Dan, you probably have reported this in the past, but a quick and admittedly incomplete search of your posts turned up nothing: How are you logging your data?

Temps started at 63F this morning and got as high as 87F then dropped back to 63F after the cold front and the heavy storms associated with it.
1) 59.7-5.8
2) 58.0-9.6
3) 61.3-9.6
4) 58.5-6.3
5) 73.4-5.5
6) 76.7-5.6
7) 82.3-4.8
8) 65.4-4.8
9) 71.4-8.4
10) 63.6-4.8
Average fot today: 64.7

Went out today, probably shouldn't have, but I had a few errands to run sometime this week, and today started off so lovely.

While I was at lunch, it started to rain. Then pour. Then hail. Did so for most of the afternoon. Combined with a 17 mile round trip, I got pretty poor MPGs. Blech. Tank average fell to a miserable 34 MPG.

14.2 mi @ 74.9 mpg @ 88 degF

Whoo hooo! Marc, that < 2000 RPM suggestion really pays off. 4th 70+ segment this week! I still might hold off a bit on EV and EBH till I really peak on raw technique. Then I can have a good differental of the EBH+EV advantage. But the do-it-now side of me says that I need to log some flight-time before the MPG challenge so I'm used to hitting EV on a failed glide. Right now I just drop to 'N' and start my timer on a failure. Usually retry every 15s or so.

I've also decided to start running with windows up & AC set to 80. I noticed some wierd behaviour like failed glides in s3 with speed > 55kph & 70c < cWT < 80c. That should be the s3 sweetspot, but no go. I thought it might be the pump (usually @ 80c) comming on, but, sure enough, that happend 5 miles later. So the only thing I could think off was that the battery was getting stuffy. Cabin temp was over 90 easy so no telling what the battery was sitting at. Only other explination is that s2-s3 trigger requires RPMs to go over 2000 at least once. This behaviour started when I began the low RPM pulse method. But it's also the first time I've been driving in 90+ weather too.

RLc, I hear ya' on the calibration. I'd break from documentation and just wing it. A simple linerar regressions work well. Last time I filled it was under actual, so I set speed +1, and fuel +3. Now distance is still short (0.5 - 1.0 %), and fuel is way short. So on the next fill I'll set speed +1 and fuel +2. Eventually I'll get it < 1% off on each. Since my car is 4% overly optimistic, I'm trying to set SG to actual, not FCD numbers.

JimboK, I'm logging with excel of course ;) . I didn't want to produce data spam durring daylight hours, so tonight I'll dump the last few weeks. In the meantime its on my vbGarage. That's where I archive the weeks data. Just click my cleanMPG brag logo in my sig.

i am SO sick of the wind. seems to me lately that minnesota has had more days with high wind than we used to get. and like the old story about school being uphill both ways, the wind always seems to be a head wind. however, somehow i am sticking at 60.9, though of course my gauge is always about 3MPG high. got cool today too, after being close to 90 for the last two days.

Whoo hooo! Marc, that < 2000 RPM suggestion really pays off. 4th 70+ segment this week!

And lo did Marc read from the gospel according to Hobbit, and many ounces of gasoline were spared.... :)


I still might hold off a bit on EV and EBH till I really peak on raw technique.


I dunno...........I had an awful lot of fun after my installs..... :)


I noticed some wierd behaviour like failed glides in s3 with speed > 55kph & 70c < cWT < 80c. That should be the s3 sweetspot, but no go. I thought it might be the pump (usually @ 80c) comming on, but, sure enough, that happend 5 miles later.

It happens very infrequently for me, but I too have noticed that odd behavior.........where stage, speed, coolant temps, & SOC level should have allowed me to glide but did not. That's where the EV (engine veto) switch is a godsend. That mystery can be nipped in the bud, and the ICE can be turned off anyway. My best explanation is that my instrumentation is not always accurate.

Commute of 78.2 for the day. Once again I fall just a bit short of that magical 80.0. But late last night while struggling to fall asleep, I had another delayed intelligence epiphany which may just put me over the top.

The best part of my ridiculously good commute in is a 3.0 mile stretch where I usually hit 8 greens in a row, drop 250 feet, and don't use a drop of gas (yes, yes, I know.......insane.......now you are thinking "he only gets 110?" :) ). This stretch always ends at a red light just short of the river.

It's a shame about that red light. I drop 50 feet just short of the light, building a good head of steam that has to be thrown away. And hitting that light at green means a subsequent long glide, sharp turn, and flat stretch with little traffic. But that red is the cost of a great 3.0 mile stretch, right?

Last night it finally hit me. Why not stick around at the top of that hill? Why not slow 'er down, pull 'er into a strategically chosen parking lot entrance, flip on the EV switch, and wait...........wait for the green that I never hit? A bit of EV juice plus the downhill will get me back up to speed without missing a beat.

So that's the next rabbit out of my hat, and hopefully the one that will allow me 115-120 going in and 80 for the day. I'm giddy to give it a shot.

A little colder today. Differences from, say, last week can be attributed almost entirely to difference in temps. Also the roads were still wet from drizzling all day. OK, I'll stop making excuses now. ;)

In addition to the 84.1 / 7.0 miles / 68F this morning:

63.3 / 6.6 miles / 57F / light rain
103 / 11.5 miles / 59F / light rain ("only" 103 this time :D)
71.3 / 11.5 miles / 54F / mist

The day's average was 81.5 over 36.8 miles.

The tank's up a few more notches to 75.5 / 446 miles / 3 pips.

JimboK, I'm logging with excel of course.
Thanks. With the detail of data you're reporting, I didn't know if you had some tool to capture it automatically in real time.

Hi Marc:

___SB (Smart Braking) is your best friend anytime you have a nasty light issue to deal with ;) I hope the new method works out for you.

___Sean, I see you are struggling with the SG-II’s accuracy right off the bat. Bring her closer to cal after two or three tanks and then you will know what you have left … or possibly what you don’t. Just let it guide you for now until you know how it acts with your vehicle.

___A cold 45 - 49 degrees F w/ light rain/drizzle for maybe ½ the commute but a solid 10 - 15 mph tail wind all the way in. 54.2 into the lot.

___Good Luck

___Wayne

The current tank remains solid at 61.5mpg/299mi. For a short while yesterday I saw 63mpg while travelling across southern New England to a family thing. Unfortunately I decided to return via the freeway because we were both dead tired and it was getting late. Set the cruise to 62mph and watched the aFCD sink. Can't have it all, I guess.

Dan, I think you are right. My speed and distance are right on with the SG though so I'm getting more and more convinced it is the fill level. I'm having a VERY difficult time believing that all the effort I put into this tank netted me less than 1mpg better than the last one where I only had the gauge for half the tank. The more I think about it the more likely it seems that the previous one was inflated by a partial fill and this one was deflated by the compensation.

Laurie, AMEN I SAY!! NO MORE WIND!!! :p

Wayne, do you think possibly a series of short fills would be sufficient to calibrate the SG? As above I'm strongly suspecting the gauge was very close and the fault is due to the fill level. Maybe drive around 200mi and fill, adjust, repeat until convinced accurate? The nice thing is that after I've got assurance it is accurate I'll never drive off with a partial fill again. By the way, are you suggesting I undo the adjustment I did yesterday? I'm thinking that might be best if it really was the fill amount.

No numbers for me today, I think. I injured my back pretty severely last night while doing yard work due to a series of freak coincidences. I'm working from home today because I can barely move. Driving is probably not a good idea in this state as I have trouble sitting up right now. :(

78mpg on a little bit different commute.

Got into a "squeze play" a couple of times this morning. I was in the rightmost lane with a big rig immediately to the left of me while a pickup, then later an SUV attempts to mindlessly merge off the access ramp into me. :( :mad:

Got my battery fixed. It was a dry cell. I took it back to Interstate and got an identical replacement, with discount, since it was still in the partial warranty period. Looks good now. According to their charts, batteries in this climate have a 41-month average lifespan. Apparently heat is really really hard on them.

But. The Odyssey picked up a nail somewhere. I'm driving it today, with pump in hand, to get that fixed at lunch. That means my wife will be driving the civic. ... :eek: ... :mad: ... :( ... sigh... It shouldn't bother me, but it really does. Wayne, what have you done to me?!!

Left work early yesterday for a therapeutic massage for some lower back pain and filled up on the way. Dumped in some ancient gas I'd been keeping for the lawnmower, then filled the rest with Shell V-Power to counteract any gums and varnish. Net cost was probably the same as a normal tank, but got rid of the old gas. I weighed the can before and after, so I should be able to figure out the fill amount from the density using about 100 oz/gal.

I left the massage right into the thick of stop-and-go rush hour traffic with 1/4-mile backups at lights. I would've used a different route, but I needed to hit the grocery store on the way home. I checked the aFCD just before getting there and found I'd managed 45.1 MPG for the trip in spite of it all...though I have no idea how. Must've been the warm temps (around 80°F).

I rode the bike in today. I need the car tomorrow morning and Friday during the day, so I'm planning to drive Thursday morning, Friday afternoon and use the folding bike for the commutes in between. That'll save 3/4 gallon of gas and give me an extra 2-1/2 hours of riding. :D

Only 50 mpg for the drive in today. 50f no wind.

Wife filled up the Accord today for 38 mpg. I was quite impressed with her effort.

psy

still sitting at 60.9. it was kind of neat last night. i was taking one of the backroads home, and i could see another HCH coming up behind me. i gave her the thumbs up when she passed me, and she waved.

i have figured out that pulse and glide not only covers my specific style of coasting down hills, but seems to describe driving to work on the 4 lane with a 65 limit. most of the time there's not a lot of traffic, so i can see it coming. i will drive in the right lane at about 55, and if someone is coming up really fast, i push it to 60, let them go by and then slow down. works pretty well until maybe the last 4 miles, when the traffic is the heaviest. then i sometimes have to speed up just to keep from getting run over.

why is everyone always in such a hurry? even though i drive 40 miles home, when i take the back roads i don't mind going 45. a whole lot less stress, and when i get home i am relaxed.

Got my 5th 70+ this week. Heading for a record!
14.4 mi @ 72.85 @ 75 degF

Marc, I like your parking lot idea.

Locutus, Daaannnggg! 103.. home run!

JimboK, I do log a lot, mainly cuz I don't know what I'll need later. SOC is kinda interesting since I've been keeping it low lately, the data shows it too. Something else I started showing is Percent of EPA (new acronym PoEPA, or just PoE).

PaleMelanesian, Bummer bout the Oddy, and the FE drop from "Other Driver". Just check my logs... I choose to calculate those values out ;). Can't take them out of the tank average though.

Since I know the exact city/hwy split, I see how I stacked up. Surprisingly (to me at least), my numbers are almost constant. Bounce b/t 110% and 120%. This week I'm off on a tear and hope to hold PoE above 125%. Weekend driving is always the part that pulls me down.

Today brings my PoE up to 128.95 (down from 129.48 yesterday).

11011011

WOW!! Hit 91.4mpg after 33mi of my commute this morning. This despite a crosswind plus an unusual number of tailgaters forcing me to go faster than I wanted to and to cut short a few glides. So I know I can do better!! Previous best was 87.6mpg. And, when I get MIMA, LOOK OUT!!!

Of course this dropped to 88.5mpg on the final mile after going up four levels of the parking garage to find a space....

On the way home last night a black [turbo?] Porsche whizzed past me with that lovely raspy engine note, license plate DX-DT For non-mathematicians, dx/dt is the calculus expression for velocity. I'm thinking of DV-DT for my bike, which is acceleration. Definitely inappropriate for the Insight.

Hey, I'm impressed, LightFoot -- someone else who knows a bit about differential equations!

Here's what I'd like to put on the plate of all those tailgaters and road ragers out there:

DA-DT

For those out there not in the know...

dx/dt = v --> The rate of change of position (x) with respect to time (t) is velocity (v)

dv/dt = a --> The rate of change of velocity (v) with respect to time (t) is acceleration (a)

da/dt = j --> The rate of change of acceleration (a) with respect to time (t) is....


Wait for it now...

JERK (j)

;)

Didn't turn out too bad, really. Got the Oddy's tire repaired. Quick and easy. We had lunch together, so Other Driver only put 10 miles on it @ 37mpg. Not bad, really, considering EPA is 33/38. Tank still above 50. :)

I was knocked down below 61mpg because of my lunch time drive but I wound up at home with 60.9mpg still on the clock. That's pretty surprising considering that I wound it up to 4,000RPM on the highway to get away from some jerkoff sitting in my blind spot.

My first good tank of the year. Filled up at Shell today and registered a 55.1 mpg tank :D

I had a fairly good FE day. Temps started at ~45F this morning and got to 54F. I didn't get a chance to move my car today so I have the average of this mornings segments then the average for the rest of the day.
1) 53.5-5.8
2) 53.3-9.6
Average: 53.4
3) 29.4-1.1
4) 56.2-8.8
5) 49.1-7.6
6) 51.6-12.1
7) 66.9-4.6
8) 64.2-5.2
9) 52.5-1.2
10) 42.8-.8
11) 80.3-8.9
12) 68.8-5.2
13) 74.4-5.2
Average for the afternoon: 58.8

I filled up today and used 4.66 gallons and travelled 294 miles for 63.1 mpg.

14.2 mi @ 70.92 mpg @ 79 degF

Whoo New record... 6th trip this week over 70. Gonna get harder for me these numbers since they are calculated by miles/mpg. As the I get further down the tank, the error introduced swings the numbers wider.

PoE went down a bit to 128.04 (yesterday was at 129.95)

11011011

Hi Sean:

___It sounds like you are a budding Mechanical engineer ;)

___Andrew, keep pushing as that 50 mpg tank is just a few days away!

___Tim if he’s in your blind spot, a little warp stealth might have worked a bit better :D

___Sledge, I have not heard much about your HCH-II this year but am glad to hear you can push her when you want too!

___Larry, 63 + is just sick ;)

___Dan, I might just tap you on the shoulder to perform some HybridFest Hypermiling clinics ;)

___67 degrees to start out and 43 when I arrived home in moderate rain … Winds were 10 -15 mph head/side variety but died off when the rains came. Traffic was the norm as of late. ~ 6 miles of stop and crawl but it wasn’t the complete stop and wait for a minute before moving again variety. Those types really test my patience :angry: I would have taken the winds and no traffic if I had my choice :) 55.9 into the drive …

___Good Luck

___Wayne

Well, despite being a crappy, crappy day, I had an excellent commute, improving my tank MPG by 1.6! It was a long commute day, with only a few stops and some excellent red light timing, if I do say so myself.

Temps in the 60's, high winds, rain, and overcast, and yet I averaged around 39 MPG for the day.

Wayne, not quite but you are close! My BS was in Physics and I also have a BA in Mathematics. I did some grad work over at Duke and my summer job was with TUNL -- at least tangentially relevant to your job, I think.

Lets just say I'm keenly aware of momentum, friction, aerodynamics, etc... Hypermiling stuff is right up my alley in the "This is COOL STUFF!!!" section. :)

Larry -- got those pics ready yet? Who says you can't have a little bling with your efficiency?

I think I'll be able to get to work tomorrow. I've taken Wayne's advice and set the offset on the fill back to 0%. If I'm right I'll have an extra gallon to work with as compared to last tank. Let's see if I can get even further on this tank! 700+ here I come!!:Banane54:

(Anyone else noticing slowness of the mileage logs to update? I put in a tank yesterday and the graph and my banners haven't updated yet...)

We took the Guzzler to Decatur and back today, each way about 187 miles. On the way down was mild side/tail winds mostly, tried to maintain doing about 62-63mph, got lucky for about 90 miles and caught a semi doing just that. Did mostly distant drafting to not get wife bent out of shape too much. Worked the hills with DWL religiously. Had sister-in-law in car behind us, turned out her best tank ever - 30mpg usually gets 22-28 she says. (You're welcome I say...):) The Guzzler pulled a best tank ever too: 19.5mpg
On the way home, now loaded with about 1000lbs of college girl stuff and 120lbs of college girl besides the Dad and the Mom, headwinds and sidewinds was now the word. I convinced wife that closer in drafting would be our only ticket, as I couldnt maintain 60-65 without having the pedal almost to the downshift point if we were fighting the wind by ourselves. Side winds were blowing us all over the place if we were by ourselves, significantly reduced while close in drafting - at a distance of about 1.5 E150 Van lengths... Well the trip home surprised me even more, cuz we mostly held about 72-74 mph while drafting, and set a new record tank... 20.5 mpg!! thats just sick...:smilingface (52):
Great fun, know I can do better, didnt get to put in the vacuum gauge yet.

Wow some of you are really turning in some incredible numbers... I'm really impressed!

woo woo, the wind finally died down, and i came home the backroads. there are several spots on this route where i can coast in neutral for over a mile. and so little traffic, i had nobody behind me all the way home. i have 515 miles on this tank and still 7 bars on the fuel gauge. if the wind stays down, i should have a really nice tank.:bananapartyhat:

i don't mind going 45. a whole lot less stress, and when i get home i am relaxed.

My sentiments exactly.

After riding home, 31 MPG to class last night in pouring rain, then 36 MPG to my wife's place. :(

Started out with a warm-up P&G out of her place this morning and wound up with only 20 MPG by the end of the road. I'm pretty sure I would've beat that with a constant throttle position, so I guess either I don't get much from P&G on a flat road or I was just doing it wrong.

In any case, I managed to pull it up to about 43 MPG by the time I got to work. 45°F, 19 miles, no wind.

I had the day off from the full time job yesterday, but I had a part time gig in town last night. 43.6 miles, 80.6 MPG for the round trip. Temps going in were in the 80s, going out in the 70s. A thunderstorm had rolled through not long before going home, so the roads were rather wet.

I filled up after the last pip started blinking on the trip home. Here's the MFD and SG at fillup:

http://www.cleanmpg.com/photos/data/500/MFD_SG_5-17-07.JPG

Calculated FE came to 73.8 for the tank, another personal best. :woot:

A decent commute to the full time site this morning: 76.6 MPG, 61F.

I left the hotel a bit early this morning to find a Starbucks. On the way back, I did a little FAS'ing. It's very easy in that little Mazda 6. I had a good glide for over a mile. Once I hit the heavier traffic, I stopped though.

Hi All:

___Boy did it get cold in Chicago. 41 – 43 degrees and a 5 – 10 mph tail wind. 53.8 into the parking lot … We are supposed to be in the upper 30’s tomorrow morning :(

___Good Luck

___Wayne

I'm not sure if it's the new battery, or that I pumped the tires to 60, but good results here.

Last night: 57.4 mpg / 10.7 mi / 80F
This morning: 58.7 / 10.1 / 58F
2 new records for me! :Banane08:

Tank at 50.9 / 350 mi. It takes me a long time to use up a tank with only a 10-mile commute!

51 mpg for the morning drive. 55f no wind. Tank is holding so far at 51.5 mpg.

51mpg for the drive home.


psy

Holy Carp, PaleMelanesian!! :eek:
(Yes, I spelled it that way on purpose ;) )

It was cold here this morning as well. I got a little bit later start as well, so more traffic to deal with and I ended up going an average of 5mph faster... but still managed a good run. :D

Temp was 39F this morning:

1) 50.7mpg for 25.4mi (Home to work)

Off to a good start on this tank -- think I'm getting a groove here! :Banane21:

1) 50.7mpg for 25.4mi (Home to work)

Not bad yourself! Your car has a lower EPA, so you're at a higher percentage above than mine. Keep it up!

Awesome tank, Jim. :)

I've come to believe that every mpg above 70 is not unlike the great ones on the PGA tour shaving strokes off their game. "Sure you shot 68...........but if you go to the range and practice for 8 months straight you might shoot 65!"

My little "hilltop green light wait" will work eventually. I'm struggling with the hypermiling gods though, who throw up roadblocks whenever I have a good idea.......just for their own amusement.

Tank at 75.2 / 91 miles

Thanks, Marc. You Texans keep inspiring me!

14.3 mi @ 71.53 @ 75 degF; Weekly PoE = 127.54%

Wayne, I'd be glad to help. I could leave her mod free till HF'07 so I'm used to fighting stage transitioning. But after HF, the gloves come off! I know she's got an 80+ commute in her. Maybe FireEngineer could work me into his EBH install schedule ;). Pizza and beer on me!

Sean/lightfoot, Ya'll are helping to flush out all the math nuts hear, check out []-mr bill[].

Jim 73.8 calc with 1mo/avg over 70!

Well I had a great drive in this morning. One of my lights is timed to cross traffic :mad: so it's always a crap shoot. Turns out I was green the whole way. Two pulses and EV up the garage and I scored another 70!

New techniques include 1400 < RPM < 2000 always. Also pulsing up to a lower target speed if my tail is clear. Found the glitch in the Stage transitions. Apparently S3 glide is only enabled if RPMs go over 2000 at some point. So as I leave the garage and attempt my first S3 pulse, I target my RPMs at 2000 < RPM < 2400. This is just one emperical sample, but it seems definitive so far. After the first glide I step back to the 14k - 20k range. Seems to have solved my S3 glide failure issue.

Tanks at 63.7 and turned before I hit the garage so it's a pretty solid 63.7. Excel told me I need to push the tank up to 64.0 on the way home get another 70+. Gotta run an errand on the way home, so it's gonna be a real battle. Wish me luck!

PS. I'll be updating my data dump in a few, so some of the numbers aren't in yet.

Are they making a noticeable difference for you yet? Other than the nice thought that not only do you look good in the car, you triple every one else's mileage on the road?

NICE!!:bananalama:

Are they making a noticeable difference for you yet? Other than the nice thought that not only do you look good in the car, you triple every one else's mileage on the road?

Actually, they are causing problems. They coast so well that I keep coming into corners and up to stop signs/traffic lights a little on the hot side.;) I can see that I'm going to have to re-do all of my glide starting points and speed requirements for the start of the glides. A really cool problem to have.:cool: As far as other's mileage, if I go by what most of my co-workers drive, I could about quadruple most of the vehicles in the parking lot. I was thinking this same thing on the way to pick up my wife this afternoon when I got blown away at the start of a 50 mph glide(speed limit 50) by an H2. :angry:

Today's numbers are a little incomplete. Here's why: I have been having trouble with my radio cutting out and the headlights flickering and occasionally going excessivley dim while in FAS since last Friday evening. I thought that maybe it was because I was doing so much FAS ing that the battery wasn't getting sufficiently recharged. So, a couple of times I put the charger on before I went on errands and I would still have the radio cut out even in the daytime. I started checking the voltage with the SG yesterday and what I saw was shocking:eek: , the voltage would occasionaly drop as low as 8.2 volts and it rarely got over 10.8 volts during a FAS; even when starting with a fully charged battery. Twice today this caused the SG to go blank and stay that way until I unplugged it and plugged it back in. What's really strange about the battery problems is that I just put in a yellow-top Optima ~3 months ago. I put my old Wal-Mart battery in that has been setting on the floor of my garage for the last ~3 months and the SG was reading 12.2-12.8 volts.:confused: Time for a trip back to Advance Auto Parts. Today's #'s:
1) 57.6-5.8 miles
2) 55.?-9.6
3) 53.?-9.6
4) 61.3-6.3
5) 64.8-5.2
6) 61.4-5.2
Average for today: 58.7 Temps today started at 44F and got up to 54F for the high. Winds were from the NW at 10-15 with gusts to 23.

You're right Larry, VERY nice problem to have. :)

Good luck with the battery!!

Any chance I could coax you to post your average speed for a day? I'm guessing mine is considerably higher than yours, but I'd be interested in finding out for sure. The drive to work for me averaged 37.9mph.

Well, the temps were perfect. There was a tad of a tailwind. The sun was shining and I was looking forward to a beautiful drive...

What the heck!! :eek:

Is it Friday already? Did everybody here decide to take tomorrow off and go up to the cabin today?! Everywhere I look it is a parking lot!! :mad:

494 was stop and go (with the stop portion at about 10 seconds -- can't smooth that out). 394 was stop and go (with the stop portion at about 15-20 seconds). 94 was extreme slow and go (can't do anything with mileage when I can only go between 2 and 7 miles an hour! Couldn't even FAS much because I kept having to come to a near stop). 252 was slow and go. 610 was pretty much normal except a panel van decided it would be fun to tailgate me (where is that DA-DT plate???). 10 is always a mess this time of the day... same deal as 94. Cripes!! I never saw 50mpg at all this trip. How the heck am I supposed to get to 700 miles if I can't get out of the <10mph stuff?? :mad:

Well, I worked it as hard as I could throwing every trick I could muster.

Temp is 70F with a light tailwind at maybe 2-4mph:

1) 49.4mpg for 35.9mi (Work to home)

:p

I have to keep reminding myself how much better this is than I was doing just a month ago. :D

I really wanted to keep all my work trips above 50mpg...

You're right Larry, VERY nice problem to have. :)

What the heck!! :eek:

Is it Friday already? Did everybody here decide to take tomorrow off and go up to the cabin today?! Everywhere I look it is a parking lot!! :mad:

494 was stop and go (with the stop portion at about 10 seconds -- can't smooth that out). 394 was stop and go (with the stop portion at about 15-20 seconds). 94 was extreme slow and go (can't do anything with mileage when I can only go between 2 and 7 miles an hour! Couldn't even FAS much because I kept having to come to a near stop). 252 was slow and go. 610 was pretty much normal except a panel van decided it would be fun to tailgate me (where is that DA-DT plate???). 10 is always a mess this time of the day... same deal as 94. Cripes!! I never saw 50mpg at all this trip. How the heck am I supposed to get to 700 miles if I can't get out of the <10mph stuff?? :mad:

Well, I worked it as hard as I could throwing every trick I could muster.

Temp is 70F with a light tailwind at maybe 2-4mph:

1) 49.4mpg for 35.9mi (Work to home)

:p

I have to keep reminding myself how much better this is than I was doing just a month ago. :D

I really wanted to keep all my work trips above 50mpg...

It sounds like you did quite well considering your obstacles. As for my speed for a day, I don't know off the top of my head, but I do know that is is nearly always 30 mph for each fill-up so I'm guessing 30 mph give or take.

Hi All:

___I had to stay over to finish some stuff at work and oh did that help the daily grind as I completely missed Rush by at least 30 minutes. Only 2 stop and crawls for about 1.5 miles in total … 54 - 61 degrees F and a 5 -15 mph head wind all the way home. 57.1 into the drive.

___Good Luck

Right now I'm holding on to 60.9mpg per the MFD despite my best efforts to trash the tank. Once you understand how to care for and feed a Prius she'll treat you very well :D . Trafic was unreal on the way home. Not in terms of quantity so much as speed. For a while I had allowed myself to think that people were responding to high gas prices, but the home-bound commute just tells me that since it levelled off at $3.20 we've gotten used to it already and resumed "normality." I kept my cool and snuck through traffic this time but I did find myself over 70mph for a few seconds while I tried to find the right-most lane after an odd merge. WS to 62mph, then another WS followed by a light regen off the ramp and it was mostly done. I was a little worried about the girl behind me on the back roads but she chilled out as soon as we were off into the boonies and quit riding up my bumper. Odds are she was just responding to pressure behind her, who was responding to pressure behind him, who was responding to the guy behind him, who was freaked out because a butterfly landed on a leaf in Brazil, stirring up a breeze that pushed over some engineer's cup of coffee that resulted in a broken accelerator pedal on a Chevy Malibu three towns over that started that whole mess. That's pretty much how I feel about traffic: nobody has any idea why they're doing what they're doing.

I might head out tomorrow evening to visit a good friend in NY on my way to seeing my brother graduate even farther away in upstate NY. Either way I've got about 400mi of driving ahead of me and I'm already looking at routes. I don't want to turn a 3.5 hour drive into an all-day affair but I have some really good options that keep the speeds capped at 55 with the exception of ~40mi through the Berkshires that can't be avoided. But that route is 40mi shorter than the all-highway route each way so I can't really lose.

I must have been a cartographer in a previous life.

finished this tank a little early because of logistics required to fill up at the same station i usually do. for 589.1 with 5 bars left, i ended up with 58.068.

Yesterday
Morning : 36.7 :( as good as the whether) heavy upwind/crosswind...and snow at Montreal the may 16th
Evening: 48.7 just better (heavy downwind/crosswind)
Today
Morning : 46.7 : hwy speed at 53 instead of the usual 56mph. (less heavy upwind)
Evening : 51.3 (light downwind)

the 36.7 will destroye my tank average :mad:

Pierre

The usual T/Th trip tonight.

95.3 / 11.5 miles / 64F
70.4 / 11.5 miles / 52F

I don't know what happened during that first trip other than that WT stayed lower than usual and I missed a few key lights. (This is the trip that was 103 on tuesday, and 106 and 108 last week in the warmer temps.)

The trip back I got completely owned by 2 lights (as in they turned earlier than I expected - did I miscount the "don't walk" flashes?), needing to make quick stops in the middle of pulses. :mad: Somehow I still pulled out a 70.x (71.x tuesday, 77.x last week).

79.8 / 23.0 miles daily average.

The tank's up a few more notches to 75.7 / 469 miles / 3 pips.

:woot:

Start off with a bang... Pulled some wicked numbers on the wife's Odyssey! Had to go up to the corner store and decided to take the Odyssey (I know, should have biked). I'd been looking for an excuse to get behind the wheel and hookup the SGII. Anyway, set SGII to defaults, set Engine to 3.5L, set Fuel to Hybrid (cuz I didn't wan't it to turn off).

22.4 up (PoE = 124%)
19.5 back (PoE = 108%)
20.8 ttl (PoE = 116%)

No highway miles.

EPA on the Oddy is 18 city ( 25 hwy, 21 comb ). Back when we first got her, we were lucky to score a 16 on a tank.

PoE of 124% can that be right with out FAS! It's a real battle to pull anything above 120% on the Prius...

Think SGII was on target, cuz that was just too cool.

Well back to Prius stuff..

Started bad, failed glides and all. My +2.4k RPM worked on the first S3 glide but failed on the second and third S3 glide. Might have to cross 2.4k before you hit 55kph. Had the usual failed S4 glide at mile 9 in the trip and had to NICE-on. Eventually I got frustrated and decided to swing by the grocery store. This gave me the chance to:

1) buy food
2) EV parking lots
3) Skip the highway completely.

Results were good. The removal of the highway was what I needed to score my 70 today. Did notice an S4 glide fail (never had more than 1 S4 glide fail). So at about 55kph I punch it way up (2.6k RPM) then retry at 64kph... Bingo! Man I don't know what's going on with these glide failures, but I'll see if I can't get to the bottom of it.

End results for the drive home:

14.8 mi @ 75.10 mpg @ 77 degF; PoE down (since I cut highway) to 127.25%

Gotta tell you... punching it up to 2.4k RPM (after a week of low RPM acel) felt like a race car driver..... Yes, people were still passing me...

Hi Dan:

___That Ody is worth more then you can even imagine. Wait until you and the gang are up here in Chicago and we take the MDX out for a little spin ;)

___I just posted my return a few hours ago and here I am again … And tired too :( Temps from 40 - 49 degrees F, winds calm, 54.6 into the lot. Summer blend E10 based RFG must have a larger increase in BTU/gallon content then the winter stuff then reported. The mid to upper 50 mpg segments are arriving like clock work in temps a 50 mpg segment would have been tough to meet with the winter RFG garbage just a month ago.

___Good Luck

Another PB yesterday for the first 33.5 miles of my 34 mile commute: 94.0mpg.

But things went downhill from there: had to go up 7 levels of the parking garage to find a space, which slammed me down to 88.5 - again.

On the way home, took my usual hit down into the low 80's on the first few miles which for some reason are very mileage-unfriendly (or maybe the euphoria of leaving work infects my right foot?). Then I noticed we had a headwind; pushed today's average back up to 85.5 at home.

Stopped for gas on the way home, finished off the tank at 81.92mpg, so I still have some work to do.....

Pretty miserable this morning, at least compared to recent weeks: 63.0 MPG @ 53F. First, somehow the timer for the block heater got unplugged. That's the second time that's happened; not sure how. Next, a steady drizzle and wet roads. Finally, uncooperative traffic. :(

Quite chilly this morning, took what I think I'm going to call route 2 in to work, and even with the stop at the McD's drive thru, managed a 31.3 mpg. Tank is at 29.2 mpg right now, down some because of horrible stop and crawl in the northern suburbs. Something is wrong with this truck, I'm leaning towards clogged catalytic converter, because acceleration if you can call it that is dismal above 35 mph. LOD on the scangauge seems to be really high despite small TPS. I know that I have to get its brainbox updated, there is a service note from Ford about high idle speed which is a problem that affects cold start (2200 rpm right off) and makes coasting idle at about 1100-1300 rpm most of the time. When it settles down sometimes to 680-740, the mpg numbers in N-ICE are quite a bit different (160-200 instead of 60-80).

84.6mpg at 60F

52f, no wind. 50 mpg for the morning drive.

psy

Home last night: 56.9 / 11.3 mi
This morning: 53.1 / 12.6 mi

This morning I took route C, to get more data points. My average on that route is 51, so this was still a good run!

Tank at 51.1 / 372 mi (hoping for at least 50 mpg / 500 mi)

Is it Friday already? Did everybody here decide to take tomorrow off and go up to the cabin today?! Everywhere I look it is a parking lot!! :mad:

10 is always a mess this time of the day... same deal as 94. Cripes!! I never saw 50mpg at all this trip. How the heck am I supposed to get to 700 miles if I can't get out of the <10mph stuff?? :mad:

sean, i am in little falls, and i don't know how you do it at all in the cities. it would make me crazier than i already am. i know what you mean about 10. even though i work right off of it, and in st. cloud, i NEVER take it home on friday or even thursday. it's just too nuts.

I was getting 62-63 round trip mpg earlier this week, so I checked the tires and had them upped again to 48psi – (another cheerful story). Now I’m getting 64-65mpg and 65+ into work today so I guess it was worth the hassle. Tank is now at 61+, ready for a fill this weekend.

14.4 mi @ 66.8 @ 75 degF

Well I've fallen :(. Tried as I might, I couldn't quite get that 70 today. Had a lot of tailgater's that caused me to EV-assist. A few of these fell over and lit the ICE. Well that got me steamed and I ended up trying to make up for it on the back half of my commute. The result was that I chased after two lights where I got shut out hard.

Well weeks still at 70.8 and PoE has dropped to 125.95%

On the bright side, I looked at my history banner and those funky over fill problems I had and made my history look real linear. So I've updated my Sig... You like?

Well I've fallen :(. Tried as I might, I couldn't quite get that 70 today.

Dan, 70s without an EBH & EV switch is like running a 6 minute mile with a suit on. Hard to keep up that pace. Excellent run.

106 to work. Still searching for that elusive 80 commute. She hangs around 77-78 and does not want to budge. Tank at 75.4 / 121 miles.

Hi Tarabell:

___65 back and forth to work now? That is some driving given the speeds! Next time she goes to 60 :D

___Dan, looking at that 1 month section tells me a hypermiler status will be coming very soon ;) Congratulations in advance!

___Marc, it is just a matter of time …

___63 – 75 degrees and a 5 – 10 mph tail/side/head wind to run through. 62.7 when I hit the Interstate. 58.3 at 30 miles out when I came up on a 6 mile stop and crawl. 1 hour later I exited that nightmare at a lousy 49.3 :angry: Pulled her back to 55.9 as she sits in the drive. Taking her up to Madison tonight to swap for a Prius I. She is just a touch under 600 miles and still > ½ a tank although a wide open and 65 mph limited Interstate (I-94 through Milwaukee and out to Madison) that I am not familiar with is going to kill this tank in just a few minutes :(

___Good Luck

More stupid, stupid driving this afternoon. I'm pretty much used to the people who change lanes in the intersection before I hop on the highway but today I wound up racing a freaking box truck. We were headed for the neck down with everybody else, me about a car length ahead to the left of him. Instead of folding into the zipper like a normal person he tries to get ahead of me to cut me off? What the hell is the point of that? It was either brakes or gas so I chose gas to close the gap and that was the end of it. But when you think about it, we collectively burned plenty of extra fuel to get to the same place at the exact same time (no faster than the car in front of me!) and increased the odds of an accident because he wanted to jockey and I don't like the marks that jersey barriers make on doors and quarter panels. W_T_F!

I'm not making my drive out to NY until tomorrow and I'm happy to be off the roads. The tank is sitting at 60.8mpg on the MFD, 396mi and three stale pips on the guess gauge.

sean, i am in little falls, and i don't know how you do it at all in the cities. it would make me crazier than i already am. i know what you mean about 10. even though i work right off of it, and in st. cloud, i NEVER take it home on friday or even thursday. it's just too nuts.

Well, it isn't a cake walk but it definitely isn't up to what I experienced in Washington DC. Today was terrible. This place gets more and more like Chicago every day. No good way around anything at all.

Temp is at 82F:

1) 46.9mpg for 14.8mi (Home to barber)
2) 47.2mpg for 8.8mi (Barber to Post Office)
3) 41.4mpg for 6.4mi (Post Office to home -- OUCH!!!)

This sure isn't helping my tank average... Though I did manage to at least get it over 50mpg on the way up to the Post Office. The lights killed it pretty quick.

I needed the car Thursday morning and thought I'd need it Friday at work, so I drove in Thursday morning, rode home on the folding bike Thursday night, rode in again yesterday morning and drove home last night. Only 34 MPG in pouring rain at 42°F for 15 miles.

After I parked the car and shut the engine off, I heard a hissing sound and checked it out; I had a nail in the tread of the right front tire. Recent tests on Gassavers appear to indicate that compact spares generally appear to increase efficiency on the rear and decrease it on the front of FWDs, so I put the right rear tire on the right front and the compact spare on the right rear. I'm glad I did, because the right rear nuts were frozen and would've been impossible to break free if I'd had a flat on the road.

The whole thing got me researching new tires in case I have a catastrophic failure; it looks like Bridgestone B381s or Goodyear Integritys in the OEM 185/65-14s would be the way to go, perhaps 175/70-14s to get a little narrower with the same outer diameter -- though I'm not sure if it would necessarily benefit FE. I think the current OD is about right for my mixed driving (30 MPH average).

:woot: Back on the horse (well for a bit)

14.2 mi @ 70.16 mpg @ 82 degF

Barely eeked another 70 out this week. I didn't fail any glides (well except for mile 9 where the pump comes on) although I had some traffic problems and a few real hard stops. I really can't get my head around what fails a glide. By my calcs I have 15-20 glides on my commute. So I get at least a 90-95% success rate.

So that brought my week down to 72.5 and PoE down to 125.6 %

Actually thought of a new figure to look at... Since most people get 15-20% below EPA, and I'm getting 20-25% above, I wanted to calculate what my Equivocal Gas Price would be.

So my Percent of EPA is 125.6% but my Percent of Normal Fuel Economy (PoNFE) is 153.5%

So with gas in Houston tonight at 3.05/gal, my Equivocal Gas Price is 3.05/1.535 or EGP = $1.99 / gal. I end up getting razzed a lot at work cuz they think I'm nuts. Told one of the good natured tormentors that I pay < $2 /gal and all of the sudden I had his undivided attention. Had questions about what system modifications I had to do, if there were additives involved

So to tie it all together, my
wMPG = 72.5 mpg
PoE = 125.6%
PoNFE = 153.5%
EGP = $1.99/gal

Rapidly running out of Excel columns.

Hi All:

___A ton of non-local high-speed highway yesterday night and this morning into Madison, WI. and back. 10 mph side/tail winds in 63 - 71 degree temps for a 53.4 out and 5 - 15 mph side winds in 62 - 67 degree temps back for a 50.5 this morning. There was a lot of idle time charging up a Prius I’s 12V last night which probably cost a tenth of a gallon at 0 mpg but I won’t count that until the final tank calc when I fill ;)

___Good Luck

___Wayne

I only had 2 segments today but they were kind of long. Winds were 10-15 mph with gust to ~25. Temps started at ~55F and got to ~78F.
1) 53.6-63.3 miles
2) 57.9-61.7
Average for today: 55.3

Hi All:

___Besides the many mornings of 40 – 50 degree temps, the run up to Madison and back in less then ideal conditions, and maybe 20 minutes of idle time to resurrect a Prius I is really showing on this tank :( 952 miles out and the low fuel has been on for the last 20 … Temps from 43 - 61 degrees with 5 - 10 mph side winds yielded a 54.0 into the lot.

___Good Luck

___Wayne

Got some interesting numbers.
1) 46.*-5.2
2) 68.6-5.2
3) 98.4-5.6
Average: I'm not sure, I forgot to check it.
http://www.cleanmpg.com/photos/data/500/medium/100_0622.JPG

The image is a bit blurry but here's the start of a bunch of these.:D

I had a great day yesterday, due to mild winds, sun without being too hot, but that nice temperature range where it's thoroughly warm without being too humid or hot.

Averaged around 39 for the day, and brought up my tank average more than 1.4 MPG!

So Wayne, no more Accord? Sounds like you've got some fun experimenting to do!!

Got some interesting numbers.
1) 46.*-5.2
2) 68.6-5.2
3) 98.4-5.6

:eek: 98.4?!?!?!?!? What did you do?? Coast down a mountain???


My numbers aren't nearly as impressive. We seem to be running through a cold snap right now. Temp is right at 50F right now. There is a few mph wind blowing and of course I had the wife in the car so I went easy on FASing on the way in. Didn't do that on the way back, though...

1) 44.4mpg for 21.0mi (Home to Church)
2) 37.9mpg for 2.1mi (Church to Culvers)
3) 48.2mpg for 22.6mi (Culvers to home)

The tank is currently sitting at 47.5mpg... I've got a lot of work to do if I want to hit that magic 700mi before filling up again...

Hi Sean:

___Actually, you are thinking of somebody else very close to our community ... Watch the news tonight ;)

76.1 / 5.8 miles / 54F
65.9 / 5.1 miles / 55F

71.7 / 15.4 miles on the day.

The tank is at 75.5 / 484 miles 3 pips.

Nope, no mountains. Coasting did play a large part in it though. As Wayne mentioned earlier, keep an eye on the news; there will be a much better explanation coming. The news is "mountainous" though.;)

I thought I was done driving for the day but I found out that my mom had fallen at her church and I had to take her to the emergency room to have her checked out. All the X-rays came back negative so I got to take her back home.:) Here's a complete set of nubers as I have them for today. Segments 1-3 are a repeat of the earlier post.
1) 46.*-5.2 miles

Thanks Marc and Wayne for the encouragement.

The weekend errands dashed my goal.... by 0.1 tMPG :o

a) 2.6 mi @ 64.4 mpg @ 79 degF
b) 13.3 mi @ 50.08 mpg @ 82 degF

Bringing my tMPG down to 63.8, giving me a wMPG of 69.8

Excel tells me that if my tMPG would have ended at 63.9, then my wMPG would have been 70.1.

Ohh well... 70 MPG week is just a matter of time now.

At any rate, 69.8 is far and away an all time high :woot:

weekly PoE of 120.9%
