I'll start it off this time.

This morning was my first with EV capability and it's a little tough to tell if it did anything from just this one sample. Temps were about 45F with light rain, moderate to heavy rain just as I was pulling in at the end. I also enjoyed a few moments of relative solitude at key points in the commute, allowing for the extra odd P&G cycle or extended glide.

I EV'd out of the drive and down the hill, then lit up the ICE for the rest of the drive. It's kind of funny to see the 5-minute bars doing the opposite of their usual, starting with one pegged bar and then dropping off in height. After negotiating one traffic tangle and hitting the final leg of the trip I re-engaged EV mode to roll through the parking lot. (Although I usually stealth through the parking lot anyway, so it's not like the button did much here. Just guaranteed that I didn't accidentally re-light the ICE). When all was said and done I was looking at 61.0mpg for the trip, a new personal best by just 1mpg. No measurable decline in SoC for the entire trip.

Sure, why not. I'll allow myself a bannana dance. :Banane25:

Temps were 55F this morning with light rain and a headwind wind gusting at 13mph. I tried a new route to work which yielded only 56.1 MPG. It was a nice drive and my average speed was 24 MPH, which would make for some nice pulses & glides. However, I was one side streets that crossed main streets, so I have stoplights at every block. I don't think I'll be taking this route again.

76mpg at 32F - not bad for this weather.

Hello

Yesterday I went to vist a old friend. I took the country roads and nailed down a 61.9 mpg for the 35 mile trip. Temps were in the mid 50's with a northwest wind. Ended up with a ave speed of 30 mph, max rpm of 2444 and max speed of 51 mph.

This morning I did a solid 45 mpg for the grind into work. Temps in the mid to high 20's with a slight southern wind.

This evening allowed 47 mpg.

Temperature at 22 degrees am. 34 degrees pm.
80.6 in to work
83.1 back home
81.7 for the day

sitting at 4.4 L after filling the tank fresh! ended up with 700 km with 34 liters pumped in, will update mileage log later tonight.

My morning segments were 45.4 to the wife's work and 48.5 from there to my work. This afternoon, I got 56.1 back to pick up the wife and 49.2 from there back home.

Yesterday I took the family out to lunch and had a good segment there and back. It was a 14.* mile trip and I ended up with 56.*mpg at an average speed of 26 mph. The trip back home was only 52.*.

4.2L/100km with 102 km on the MFD display then two more segments, after that the car is sitting in the garage since i'm going on vacation. So I better read up on how to store your prius for the longest amount of time (3 weeks).

While i'm on vacation i'll get to drive a 4WD Rav 4 wee! So that should provide some interesting times.

36 degrees this morning on the way in, but managed 63.5 mpg for the 30 mile segment. Light traffic on secondaries allowed for some 45- 35 mph P&G.

Poor commute, and not because of the FE. Passing me illegally while I do 35 in a 35 on a dead-empty road is one thing...I can live with someone's impatience as long as there is **some** level of attention to safety. But passing me while I do the same speed in the same place with children waiting for the school bus is over the line. That was the second attempt to pass...the first was thwarded by a schoolbus loading children.

I've had it with these people acting like the 45 seconds they will save on the way to work in the morning is more important than a kid making it to school in the morning. Or a parent making it to work. Or even the family dog standing a chance if he gets loose. The other thing that kills me is that somebody will read this and immediately blame it on me because I was "going too slow." As if somehow paying attention to the numbers on the signs poses the safety hazard.

59.2mpg, 32F temps. Angry for the first time in a very long while.

31ºF this morning and only 53.3MPG in to work for the 13 mile trip. I did take the highway though. I only got 52.6 MPG (58ºF) on the way home yesterday, but again took the highway.

73mpg at 40F - I'm slipping.

Mid 30's, slight head wind for 46 mpg.

Mid 40's, slight tail wind for 48 mpg.

You will get no argument on this from me. I was on a Yahoo group a year or so ago and somebody went so far as to say I should be shot for thinking it was ok to go the speed limit in traffic.:mad: It got so bad that the moderator had to edit the thread. He then sent me an apology by PM. Needles to say, I haven't been back there since. People doing what you described above makes me wish I had photon torpedo or two and a fully charged phaser bank. :D :Banane36:

My SG lost it's mind today so I only have partial info. I'm going to have to go top off tomorrow and start over. I think I have just enough miles to hit the 5K mark...;)

24 degrees am 19 degrees pm

82.7 to work
70.2 back home
75.9 for the day

To work- 77.8 MPG @ 39 deg. F
Low fuel level light came on coming home, tank ended at 724 miles, 76.1 MPG by the FCD, and 71.05 MPG calculated.
After refueling, arrived at the house with 94.6 MPG showing on the FCD (only 4.9 miles)
Starting a new tank with colder weather predicted!

30ºF this morning and 53.3MPG using the long route with all the stoplights. I think I'll keep this route. My mileage should go up once I learn the lights.

57 mpg with colder temps, light rain and two cold starts on the way home yesterday afternoon. Dissapointed, but doing the best I can with what I'm presented with.

30 degrees this morning with 61.5 mpg and some crowding on my '6, but I'll take it with these cold temps.

After reading about Wayne getting 80-something mpg in the Winter, I went home getting 83.4mpg, but dropped to 80.6 during miles 24 and 25 at the end.

This morning only got 72.6mpg (where personal best was 88).

I filled up gas today and got a lousy 38.02 mpg!! :(

The worst I have gotten since I started hypermiling is 39.5 or so. I think I went to a different pump at the same gas station and was sloping down more than the other pumps. I don't know if that could be the reason. According to my SGII, I should have gotten closer to 42. I would have been happy with even 41. Instead I barely made 38!

Hopefully I can bounce back with the next fillup.

Hi Tim:

___About your School Bus post, you were following the limit and there were children about. I would have been on the cel reporting those a$$es at my first clear opportunity.

___Everyone else, just hang in there. A few more weeks and we will be seeing those 60 + degree temps some of the time and then there are going to breakouts! Half the members are already blowing through the EPA in mid-winter. Just wait until summer and this forum lights up with nothing but smiles :D

___46.3 out to Detroit with a light tail wind, high 30 to low 40 degree temps and some rain. On the way home in 24 - 30 degree temps and a strong headwind the whole way … I was searching for targets to hide behind all the way home. Still pulled a 43.1 although that sucks :(

___Good Luck

___Wayne

28 degrees this morning with 61 mpg coming in, but the only reason this happens is there is no traffic so I can dawdle between 35 - 45 in a 55 mph zone and nobody gives me grief. The batteries get cold soaked in the parking lot during the day, heavier traffic on the way home and it looks like 56 mpg will be about the best I can do. I try to park at the end of the row with the back of the car pointing towards the sun to try to keep tha batteries as warm as possible, but it's probably only wishful thinking. I have no scan gage to measure actual temps.

Winter temps really showed up this morning: 19F with a light coating of frost on the windshield. That thermos bottle didn't retain much heat so I had to run the ICE for 5min before the windshield would quit frosting over. Then my hands were freezing so I left the climate control at the minimum of 65F. I became comfortable but the ICE wouldn't shut off under any circumstances, with water temps hovering around 165F. Long story short I ended my commute in the mid 40s and only after shutting down cabin heat after the windscreen was completely thawed...before that I was seeing numbers in the high 30s.

I too had to run the heat this morning. It felt a lot colder than 28ºF. Only 48MPG coming in to work.

Hi All:

___20 - 25 mph headwinds the whole way in 38 - 44 degree temps … With the 2 Stop and crawls of maybe 3 miles 3 miles she still saw 43.1. This tank is sitting at just 44.1 (add a little with my negative offset) but it is not going to be pretty with the trip from Detroit and today’s run to work with these monster headwinds. Oh well, it was a lot warmer these past 4 weeks then what we have coming into Chicago next :(

___Good Luck

Sounds like you're going to get it just before I do here in northern IN. Next Tuesday and Wednesday the high temps aren't supposed to make it out of the teens. It's also supposed to go to -5F Tuesday night.:eek:

Today started out at <30F. There was also a good stiff breeze from the south. The trip into the wife's work was 53.4 but from there to my work, I only got 49.0. Lousy headwind.:( This afternoon, the temp was at 42. The trip back to pick up the wife was 56.1 and from there to home was 56.2.

I can't wait to get out of winter, get the snow tires off the car, and get the factory sludge out of my crank case. Filled up on the way home (for the first time in 10 days) and calculated a pathetic 49mpg. I'd love to blame this one on the tank bladder but I get the impression that my FE is just that mediocre.

Hi All:

___Brick, you are still learning. And get those Snow Tire meats off that thing and that oil swapped out like yesterday ;)

___DiamondLarry, I would hate to see what you would do with a Prius II or HCH-II in the summer months!

___Skwyre7, I will have to look back in the intro forum to find out about your commute. 28 degrees and you are still pushing 10% above the 08 and forward EPA specs is still pushing it in my book.

___Bob, Holy smokes, 60 + in an HCH-II in below freezing temps? I bet you push your car down the drive to get her moving like I do sometimes, don’t you :D

___Eric, Chuck and HawkGT, here we are slicing and dicing with sharp knives and other Ninja like utensils and you guys keep pulling out your automatic weapons. Darn Insight’s anyway :D

___Psy, I know that 60 mpg tank will be in your pocket a lot sooner then you think. Just keep holing that lmpg up because you are only another month or two away from the wild stuff!

___Although winter is not nearly over, I hope everyone is ready to pull out the big guns when we hit those wonderful 55 + and sunny days just a few months from now :)

___Drive home this evening with that 15 - 20 mph tail wind helped but the traffic was a mix of 65 + back down to 0 - 15 stop and crawls again and again. 52.7 to show for the effort with a 45.2 mpg tank showing now. I was really starting to push knowing how badly I have been driving this tank to help bring her to a winter norm.

___Good Luck

OK

Yesterday morning I had to go to the Creek Indian Hospital in Okemah, Ok. and check out a boiler operation issue. The feed water pumps aren't keeping up. Was a real waste of gas. A over educated college boy strikes again. He spec'ed feed water pumps with a max psi, of 15 psi for 15 psi boilers. DUH!!! and he wonders why they wont pump water into the boiler at operating pressure. So going to the hospital with a 15 to 20 mph head or cross wind netted me 42 mpg. The trip back to the house was good for 48 mpg. Same cross winds and now a tail wind. I expected better. I then went on into the office with a tail wind for 52 mpg. temps in the low 30's for the morning drives.

The evening drive was a disaster in the making. The winds were howling out of the south at 15 to 30 mph. Temps mid 50's. I fought it for about 10 miles. I was loosing bad. Then here before me I see half of a double wide mobile home on the hwy with no rear escort truck or car. I set myself up for a distant draft, 3 to 4 car lengths behind him. Follow him at a slow 45 mph. He gets off the hwy after 20 miles. I get a few, semi good fas in after his departure. End the evening segment with a 48 mpg run.

Today I take off for work with a good tail wind and net a solid 51 mpg for the morning segment. Temps in the mid 40's.

This evening temps playing with the 60f mark, winds out of the south 15 to 30 mph. We are being set up for a ice storm over the weekend. :( I could find nothing to draft,, no protection. After 15 miles of this nonsense I went into normal driver mode. Got in the fast lane and hit the hammer. got a solid 40 mpg for the drive home.

Filled the civic up for a 44.2 mpg tank. I was stunned at the low hand calc's. The SG had me at 46+ mpg for the tank. Was a lot of hard driving to be lied to by the ugliest piece of auto equipment Ive ever seen. This tank was done on 91 octane. I filled it back up with 87 octane. I feel the car runs better on 91 and pulls harder as long as you stay in a narrow temp range of 45 to 80 degrees. Get below or above that and it loafs around like a wounded duck. O well.

I was impressed with the 40 mpg for this evenings segment. Even if I factor in some error for the SG. I know it was epa or above for the drive home. The Civic really impresses me with its offering of epa or above when I flog the crap out of it. I have to wonder what some folks are doing to there Civics on other boards that cant get half of the mpg I get. And swear they are not driving it hard.

psy

Wayne- My day got even better later this evening. I had to take my wife to the beauty shop(like she needs it:) ) then on to the hardware store. Overall, the trip was ~15 miles. By the time I pulled into the hardware store, the SG was sitting at 53.*. 75% of the trip there was into ~10mph headwind. I was workin' the injector kill switch real hard. On the way back, I went on home to wait for the wife to call for me to come pick her up. Since ididn't have to make the stop I did when I dropped her off, I took a more rural route and the best part was, it was the same length. By the time I got turned around and headed back down my drive, the SG was at 65.0. When I went to pick her up, I made a detour to pick up a pizza and the round trip of ~20 miles ended up at 53.* by the time I got backed into my garage.

As for those summer numbers Wayne mentioned earlier, if anyone would like to lend me thier Prius or HCH for a few weeks this summer...:D

It's a wonderful morning! 43ºF with light winds and a new route to work. I'm very happy with my 60.9MPG. I think I'll be using this route from now on.

Filled up last night, 57.1 MPG for 575 miles (**** soft winter tires). This morning 50F and decent traffic, ended at 66.7 MPG to start the tank before next weeks temp's in the teens.

Wayne

Doing much better this morning. No frost and 39F temps, result was 59.2mpg after touching 66.1 before the usual highway fuel dump. Waking up and getting out the door 10 minutes earlier payed off in the form of zero harassment, and only one follower (large SUV no less) who kept a ~300-500ft following distance and may have been using a little DWL within a similar narrow band of speeds. I'm going to spend this fresh tank pushing as hard as the weather and wackos and will let me.

Did 73.5mpg at 65F, but avoided P&G to check out my CarChip.

Yep. :)

This morning, there were two (2) accidents on the road I take to work. The first one had me creeping for 35 minutes. I did not have time to shut down between creeps. At least, I didn't want to have to power up when it was time to move again because it was hard to tell when that would be. The pack did great for the first ten minutes but I could see it getting low. Then the engine kicked in; no end in sight. I creeped with the engine intermittently running for more than twenty minutes! Almost a whole screen of segments BELOW 25.

Then things were normal and I was able to regain some of what I lost. I knew it would be a challenge, but I was gliding and stealthing and coasting as much as I could.

Then the second accident. The accident was about a hundred times worse than the first one in terms of wreckage. But as far as I was concerned, I wasn't sitting for as long this time. Granted, the now-full pack once again drained as I creeped in traffic resulting in another few sub-25 segments.

In the end, it was a horrible horrible drive this morning.
On the up side, I got gas last night so I have a few hundred miles to work on getting tank average back up where it belongs.

Tony,

I'm guessing the heater was not much help as you were waiting. :(

For an Insight, not only would my fuel economy tank, but it my State of Charge was borderline, gridlocked traffic would make a recal and ideling engine certain (Resistance is Futile).

Hi Tony:

___Sorry to hear about your morning stop and crawl. I had to battle the standard Chicago Suburbs - Friday night in the rain love fest from Rt. 53 to I-294 on I-55 Northbound and then again from Lake Cook all the way to Rt. 137 on the Tri-State tonight. It was a 2 hour and 45 minute SOB over 65 miles but nothing like what you experienced this morning! 45.8 per the SG-II isn’t to bad given the 38 to 42 degree temps and hellacious traffic mess … We have to get together and take your Prius out in the thick of it sometime so we can compare notes wrt the Prius II’s capability in the dense stuff. I have some ideas I would like to try out as they work really well in the Accord and they may be able to be carried over to the Prius II with some very aggressive throttle control.

___I filled her tank tonight and ended up at 47.8 over 906.9 miles. I think I am going to keep the SG-II’s negative offset at - 9% so I have something to battle against every day as it is so nice to gain a few mpg’s when the final number comes in :)

___Good Luck

Way to go, Michael. Just curious: What route did you use?

It sounds like the days of good numbers may be over in this neck of the woods. Morning temps started at 48F and got up to 51F. The morning trip to my wife's work was 49.5 and 50.6 from there to my work. This afternoon I had 54.1 on the way to pick my wife and 55.0 by the time I got home and got backed into my garage.

Way to go, Michael. Just curious: What route did you use?

Midlo to Hull to Belvidere and up. Not the best area of town, but I don't have to go above 40MPH.

Last night we drove into Roanoke, VA and got an amazing 52MPG! The best I've gotten on that trip before was 47-48MPG. I'm hoping for another 55MPG tank, so I've got a little work to do.

Good morning from ice laiden Oklahoma.

Yesterdays grind was a wash. With the storm coming in. It was a dog eat dog drive. When I left the house yesterday morning it was 61f with light rain and a northern wind. 5 miles north of Okmulgee it was 50f. Same winds with rain. By the time I got to the office it was 34f and falling fast! Rain with sleet mixing in and a strong north wind. This segment came in at 41 mpg.

The afternoon drive was really a midday drive. We shut the office down and abandoned ship at 11:30 am. The temps had dropped into the the upper 20's with freezing rain and ice covering everything. I scraped the ice off the Civic, sprayed rain-x deicer on all the windows. Fired the car up and off I went right into some bad Tulsa traffic in a ice storm.... LMAO. Had to get to a pcclub to pic up some ram and a video card. Anyway the drive home was a mess. Bumper cars sums it up best. With ice covered roads and accidents everywhere I managed 38 mpg. Didn't get hit. Didn't hit any body. Made it a success in my book. And still managed epa hwy. :)

OOO the video card,,, a EVGA cheapish 6200 will get the job done for the media pc I'm building. Will be the last AGP card I ever purchase. And the ram is junk! Even Corsair can make junk I guess.

We shouldn't be doing any driving here until Monday or Tuesday. We are hugered down for the storm.

My girlfriend and I have been hauling big heavy things around in her XC70 all weekend with surprisingly good results. Our combined efforts have kept that beast just shy of 28mpg (117% of EPA highway) even despite her somewhat less attentive driving style. The tank impresses me sometimes. (A little.)

I did the Hybrid math for her a few weeks ago and discovered that she would actually save substantial money by dumping that thing for a Prius over a 5-year time frame. She likes my car and wants me to re-run the numbers in a year :D.

I haven't participated in the "Daily Grind" threads to any degree, but I think I'll jump in. Maybe not as regularly as some, but anyway, here we go ....

Temps of about 70 the last couple of days, and it shows. I filled up Friday night. I used a favorable cross-town commute route yesterday. Today my fiancee and I went house-hunting, mostly in rural areas ideal for P&G. The result: Current tank is sitting right at 65 MPG after about 150 miles. I had a fleeting hope of a 60+ MPG tank at next refill, until I remembered the weather forecast for later in the week: highs in the low 40s, lows in the low 20s. That must be psyshack's Arctic blast ... hopefully without the ice!

I had to go up to Flint from Detroit area on Sunday. I drove the Aztek with the wife and kid. I wanted to see what I can do on the highway so I reset the Average MPG and away we went. We had freezing rain all morning and it was still raining out. I’d say about 34F on the way there and maybe 36 on the way back.

So I limited myself to 20 MPG instantaneous reading climbing hills/ overpasses and a top speed of 65 mile/hour. When I started to loose speed up a hill I added throttle to the 20/21 MPG range. I would try to stop my speed from getting slower and would hold that speed if I could. I rarely got below 60 mi/hr. I finally broke 26 mpg on the highway. No other techniques were used and most of the time I was getting passed on the left with no one in front of me.

I found out quickly how sensitive the accelerator is to input. The slightest change made my MPG value move at least 1/2 mpg. I was impressed that such little change in the accelerator was all I needed to stay within the 60-65 mi/hr range. I did dip twice down to 57 on a long climb up a hill.

So is this the correct way to do the DWL technique? Maybe next time I will try to limit the instant MPG to 22 and stay above 55. Any advice appreciated.

Sunday afternoon I went 20 miles - on the treadmill.

I was in the EV mode the entire trip. :D

71mpg at 25F today. Might have been at least 2mpg better, but among other things someone decided to go 30mpg on the overpass from I35E to I635, even though the roads were free of ice. :mad: It's one of two big ramps on the way to work that go 60 and 80 feet over the ground. When possible , I try to get to 60 or so to avoid using the throttle heavily climbing.

20F and a measily 35mpg. Bahh. 1 more tank until spring. I can't wait.
