Quite the week so far! Sorry about the server downtime -- do let me know if something is still not working properly.

I'm not driving today and didn't drive on Monday but did drive yesterday. It was a PR in the morning. :D The way back wasn't because of traffic but I'm happy anyway. I didn't think I could hit that high on this route... and in mid 50's degree weather, too!

56F in, 6mph tailwind from the NNE, overcast,
63F back, 10mph headwind from the NE, overcast:


123.1mpg for 15.0mi (Home to work :woot:)
105.0mpg for 15.6mi (Work to home with a slight detour because of road construction)


Day Total: 113.2mpg over 30.7mi

Nice work, Sean!

I'm at about 78 cumulative for this week. Getting down to 1/4 tank so I'll fill soon. School lets out next week so I'll have the good commute for my whole next tank. ;)

I had a pretty good day yesterday.:)
http://www.cleanmpg.com/photos/data/500/Good_day_on_the_Insight.jpg
The temperature yesterday was 80F but I forget the wind data. I filled up in anticipation of having to make a trip to Cincinnati on Friday; seems there is some guy my daughter is fond of there.:p The trip to Cincy is around the 250 mile mark. My goal is an absolute minimum of 80 mpg but I want to shoot for high 90's or 100. I think there is rain predicted then though.:( On the high FE leg, I maxed out the FCD in less than a mile and maxed it out several more times until around 8 miles or so out.
74.2 1.2(home to bank)
132.3 14.5(bank to gas station via FE friendly route-VERY FE friendly:D)
115.6 12.6(back home)
Day total was 120.6 over 28.3 miles.

Fill up numbers were 8.563 gallons over 771.4 miles for 90.1 mpg. Not too bad for having all of the rushed-for-time driving.:)

Not sure if I'm driving today or not but, I am driving to Cincinnati early tomorrow morning and returning tomorrow evening. For some reason I thought the trip was ~250 miles each way but, it turns out it is more like 277 mile.

No planned driving for me today.

Oops, I forgot to edit the route on my end of the trip.:o I knocked off about 3 miles and have longer for warm up P&G and only added 2 minutes to the trip.:)

Will be driving down to St. Petersburg this evening (hopefully kid will fall asleep for a longer time ;)). This car doesn't do well for long trips :( FE tanks after 50mph or so...

Averaging 61.53 over 217.2 miles commuting so far for the week – two legs (one to work, one homeward) were 64+ mpg :D Time pressed, other humans in the car driving has the tank average down to 58. Upside: I left one of my partners astonished after I telling him we used less than 2 gallons as we pulled back into work after an 84 mile round trip...would of been +4 in his truck.

Thought 65+ was going to happen this am with an 8 mph tailwind, but a line of traffic kept me from slowly gliding down to two critical stop signs on the two lane 55 psl portion of my trip. Will try pulling over or a multiple reverse pass next time the I have the opportunity.

Killed go homing yesterday by a 14-24 headwind and disastrous route selection (why did I stay on the interstate :mad:), only ideal traffic conditions and careful gliding over the last 4 miles pushed it over 55. Crossing the Mississippi without adding onerous miles complicates my routing…more (logged) experimenting is in order.

Good work, Larry! :thumbs_up:

Brandon, are you using high speed P&G at all?

Way to go, All_about_the_glide!!! :woot:

mpg / miles
74.7 / 10.5 - home last night
70.1 / 10.4 - this morning to school and back home
61.0 / 4.9 - back to school for Kindergarten "graduation"
102 / 7.6 - school to work :D :woot:

Only one more day of school delivery in the morning. :D Then it gets good.

The tank is still at 74.5 / 813 miles and down to 1/8 on the gauge.

Sean, I am, but I may not be doing it effectively... plus essential A/C use and unwilingness to FAS above 50mph due to grinding when re-initiating gear at higher speeds (yes clutch is depressed for a few seconds first). Am I doing something wrong?

If your Kia is like my Hyundai the 5th gear synchronizers are a bit cranky when coming up from a FAS (as in, it doesn't want to engage in 5th when the engine is off). There is a simple solution if so. Pull the shift lever down (toward 4th) just a little to spin up the synchros and then shift into 5th -- it will drop right in if you do this (again, assuming this is what you are describing and the car behaves like my Elantra).

By the way, this isn't due to wear -- it has been like this from new.

As for AC, another member (who sadly isn't posting here any longer) did some tests and found that FE is higher if you have AC on during the pulse and off during the glide when using NICE-ON for gliding. If you are doing it the other way around, try reversing to do it as described above. If you are FASing you don't even have to worry about it. ;)

When I drove my wife around more than I do now, I'd pulse with no AC and glide NICE-ON with AC (on full cold so no engine heat is mixed in) when needed. I consistently topped 50mpg on the highway doing this and usually managed about 52mpg (sometimes higher). Lower speeds, no wind, and flat land obviously improve the numbers.

Give it a try and see if your numbers improve any.

Yeah, my thinking on the AC is in agreement... my thought was that the load hit wasn't as bad if you're already at 80% LOD ;) I probably won't get to FAS much as it is simply too hot... that, and on the trip back from Kissimmee, I kept getting alerted by the UG to a pending trouble code of P0449 - evap valve issue, wondering if I should keep topping off. The UG annoyingly showed and beeped loudly each time the ignition was turned off then on... then the MIL came on... I reset it and it went out and it hasn't come back. I just kept the car on after that to avoid wife grumbling every time it beeped.

That reminds me of the Fiesta when it got below 50 miles to empty. Every FAS it would "tweedle-dee" about low fuel.

The biggest advice I can give is just to watch the trip average and try to make the mpg ratchet up with each and every cycle.

I would probably nice-on with AC for a trip like this, too. Family on board and all... ;)

The weather was against me today. The temperature was 53F and the wind was NE@ 5-10 mph. There was also light to moderate rain which meant wet roads with places of 1/4-1/2" of standing water. There were also no really clear ridges to ride either.:(
99.1 6.7(to daughter's school)
93.6 8.1(back home)
Day Total: 96.0mpg over 14.8 miles.

Tomorrow's trip to Cincy is going to be interesting as we won't be able to leave as planned at 6:00 am. It may not be until noon that we'll get to leave so I'm hoping I can miss the Kokomo and Indy rush hours.

The day has started pretty decent so far. I took my daughter to school so she could finish up some testing for graduation. The temperature is 47F and wind is NNW@ 5 mph with occasional gusts to 20 mph. Headed to Cincinnati later this morning so the numbers are going to go down. Hopefully not too much.;)
95.4 6.7(to school)
114.2 8.1(back home)
Day Total: 104.8mpg over 14.8mi

Very nice, Larry!! Just remember those suggestions I made about highway travel and you should do just fine. :)

74.5 / 10.5 - home last night
87.9 / 8.8 - out to music practice
76.1 / 8.9 - back home
67.6 / 12.9 - this morning school and work *

* the line at school was long and ugly. :( Thankfully it's the last day for this year.

The tank is at 74.6 / 854 miles. I saw the Low Fuel warning on an hill climb this morning. Time to fill.

I filled up at lunch. SG said 74.5 / 857 miles. Actual:

857 miles
11.70 gallons
73.25 mpg

Slightly low, but I KNOW the tank is full. School is out, my commute is good, my tank is full... ;)

The numbers are a little low, partly because of my 320 miles to the airport and back - for the F150/Fiesta drive. Commute for a week, drive to the airport, drive back from the airport, commute for two more weeks. You know you're a hypermiler when...

Well, I fared alright, but I've pretty much maxxed out this car's summertime open road potential with A/C...

Yesterday
38.5 MPG / 3.2 mi home to Texaco (fillup @$3.499 :eek:)
58.3 MPG / 5.2 mi Texaco to FSU
41.9 MPG / 2.9 mi FSU to home, finish loading car
40.1 MPG / 170.5 mi home to Crystal River (dinner/diaper change stop)
46.9 MPG / 77.9 mi Crystal River to Pinellas Park (inlaws home, higher due to lower speeds in more occupied area, less A/C after sun went down)
43.3 MPG / 7.3 mi round trip to CVS (son was running 103 fever when we arrived :()

Sean, the suggestion of popping 4th quickly, then 5th before bump starting helped a lot with the grinding issue. The P0449 code came up again, but I found the setting in the UG to disable the audible alarm, so I happily P&G'ed in silence, and wife was none the wiser :D. I also found my P&G sweet spot so to speak... 29-30% TPS and ~70% LOD on the pulse. Any higher and it just lowered MPG without really accelerating any faster. Does this match your experience Sean, or should I keep exploring. This configuration seemed best whether A/C was on for the pulse or not.

Well done, guys!! :thumbs_up:

Brandon, I'm glad the slight pull toward 4th is helping your shift to 5th. :). Unfortunately I still don't know what TPS or exact LOD values I'm running because I do it by feel. High speed P&G can be treacherous; if you don't have your timing down to a T it can make your mileage worse very easily. I recommend keeping both instantaneous and trip average MPG gauges up and concentrating on making the average higher at the end of every glide than it was at the end of the previous glide. It is a lot harder than at slower speeds because the glide distances are so short but with instrumentation and dedication you should be able to manage higher numbers than you've seen so far.

Keep up the good work!!

Yeah, the perpetual "make the average a bit higher every glide" has been the mantra, and it worked to a point, where speed, A/C, time and weather become the decided/deciding maximizing factors. I may be able to squeeze out a bit more, and will have to experiment on the way home in about 2 weeks. Thanks for the encouragement, now I just need more support on this end. ;)

It was an AHA moment for me to realize the key is to make the GLIDE end higher, rather than the pulse. If you focus too much on the pulse you'll end up making little pulses that don't bring the average down, but the short glide can't make up for much either.

The trip #'s didn't turn out near as good as I had hoped.:( It never got past 50F yesterday and I also had a 45* headwind of 10-15 mph for about half the trip. Also, I'm definitely not used to driving a vehicle yet that takes so much planning ahead to negotiate steep hills.:p There were so many hills that were steep enough and traffic was horrible that I was struggling to keep a minimum of 45 mph. The OH state po-po was very busy so gaining extra speed was a definite no-no.;) The trip home today wasn't a whole lot better as the trip between Cincy and Indy was with a 45* headwind of about the same as yesterday. However, it was quite helpful from Indy to home. I struggled to to hit right at 80 mpg as I reached Indy but had it up to 85.0 mpg over 285 miles when I pulled in the drive today. I pulled into my daughter's boyfriend's house yesterday with 83.6 over 305 miles. The mileage difference was due to missing the turn yesterday onto I-74 and, since I was on a circular I-465, I didn't notice until I had went about 12 miles too far.:o I was able to do the round trip with 6 bars out of 20 remaining on the guess-gauge.:)

It'll come with practice, Larry -- and even at the rate you managed there is no way you could have matched it in your Prius anyway. :)

No kidding Sean. Those conditions in the Prius would have had me down in the high 50's or maybe the very low 60's. I think I have enough left to go to my cousins for lunch tomorrow in Ft. Wayne which is 83 miles each way. At 5 bars, about how much fuel is left?

I'm interested too! I am at 5-6 bars now and close to 600 miles. :D

Mike, I think I'm just a touch over 600 miles. I think I had around 30 miles before the trip. Tomorrow's trip will put me well over 750 miles. I'm hoping there is at least two gallons left.:)

This past week in spite of some rain, gusty winds and unseasonably cool temperatures I got my best tank of gas thus far: 55.5 mpg in my HIH-II. I'm up to 51.2 mpg for the life of the vehicle.

Not too bad considering the conditions I had. On the way to mt wife's cousins' I had direct headwind of 15-20 mph with gusts to around 30 mph the first ~20 miles then, I had a 90* cross-wind the next ~45-50 miles then finished off the trip of 83 miles with more 90* cross-winds. The trip home was a bit worse.:( The first leg of the journey back started with 45* tailwinds of 15-20 mph. When we got to the middle portion of the trip, we had 45* headwinds from the SW with about 20-25 of those miles with a moderate to heavy downpour. The winds had shifted back to a due south wind and cut back to 15-20 mph. When I got to Nappanee, IN, I took a small detour to the gas station as I hadn't filled up from the Cincinnati trip on Friday and Saturday. In all, the trip today came in at 83.1 over 170 miles which included a 134.1:) over 8.3 miles coming home from the station. So, for an all highway tank (-approx. 30 miles around home) with less than favorable weather I was still able to open up a can on the EPA ratings with 81.5 mpg over 809.6 miles. The tank is now at 134.1 over 8.3 miles with 20 bars on the guess-gauge. Now, if I could just figure out how to get the car to draw in fumes all the time and not just after a fill-up.;)

Not bad for the conditions. :) Gives me a good idea where i will end up soon. :p


I was wrong. I have 7 bars on the guess guage and tank sitting at 587 miles.

You'll get there Mike.:) I had 2 bars showing and I was very surprised it had not dropped to 1 since it was well over 40 miles (probably closer to 50) since the drop to 2. The fillup took 9.935 gallons.

Mike, I looked at my 1600mi attempt thread and back calculated to determine that I used about 2.55g from 5 bars down to very close to fuel starvation. Each bar seems to represent very close to 0.42g or so.

Hmm, that means I may have been around 1/2 gallon left then.

It was nice day today. not much traffic at all for my trips back and forth to work.

86.7- 7.1 miles to work. I fas'd half way up my street and bumb started when i saw was clear to move onto main road, then i stalled it! :o I was in second at like 5 mph. :p Luckily there was no traffic coming and i restarted and moved on my way. :)


93.2- 5.0 miles home. caught my work light and the next 2 also! Had a truck behind me and next lan was clear so I was wondering why didn't he move over?? He was turning right at next intersection and was patient enough to wait me out. :flag:

Tank sitting at 77 mpg- 599.3 miles.

It was a very nice day as far as the weather goes...FE #'s too.:) The temperature when I went for my little run was 81F and winds were S@ 5-10 mph with gusts to 15 mph. The trip out was primarily south with 2 miles heading east and 1 mile headed west. The trip back was just the opposite.
127.8 8.3(test run to my daughter's school)
147.3 8.3(back home)
Day Total: 136.9mpg over 16.6 miles. Gotta love warm temps in an Insight.:):Banane59:

Way nice, Larry!!! :woot:

Thanks Sean. I'm already thinking of ways I could at least bump up the return and max out the FCD. Doing so on the way there could be trickier as the terrain profile is better coming home since four of the stops on the way home are after a downhill stretch. I basically got up to speed slowly and FAS'd up to the stops. There were 6 stop signs and the stop when I turned around in the school parking lot to come home. I'm also wondering if some of the high numbers may have been a little residual effects left over from the fillup yesterday and not totally due to the weather? I don't think it was the pack voltage as it was nothing special at 168V.

I helped some friends move on Saturday. The truck/trailer and two vans were the primary movers, but I had some stuff in the civic as well. Included are short segments of car-shuffling at each end for easier loading/unloading.

mpg / miles
65.9 / 8.2 - to an event with the family, took both cars
79.9 / 5.5 - event to friend's old house
43.0 / 2.2 - to new house, loaded and car-shuffling at both ends for loading/unloading
52.3 / 1.9 - back to old house for pizza
83.3 / 4.9 - to another friend's house for cards and chips
84.6 / 13.9 - back home

That brought the tank to 74.3 / 53 miles.

I needed to go to my bank today so I took the "long" way back home.;) The temperature was 81F which was about like it was for yesterday's trip but, the wind was much stronger today.:( The wind was SW@ 10-15 mph with frequent gusts to 30 mph.:eek: On the bright side, the trip to the bank is a new PR.:flag:

80.1 1.4(to bank)
120.3 14.0(back home via my grandpa's old place :p)
