I'm currently hyp-o-miling a Pontiac G6 in southern California. Gas mileage? Yes. Let me just say that my Boston driving skills came in really handy on I-5 today. :eek:

...maybe I'm starting to catch on, brick. :D

The temps started out at around 43 this morning. Today was my first morning with my block heater. I went the cheap route and got one for the lower radiator. Saturn's choice to put the thermostat on the engine side of the lower hose may prove slightly less effective though. My numbers this morning showed a slight improvement. The trip to take my wife to work was better than usual at 40.3. From there to my work was 58.4. This afternoon's trip back to pick up the wife was 61.4 and from there to home was 56.2.

Only a stinking 39mpg for me today on the way home. Which contrasts the 50mpg I got on the way in. Stinking traffic and rain. A bad combo.

Hi All:

___Traffic was so bad this morning (24 mile stop and crawl ahead) that I stopped at the Park and Ride at I-55 and Rt. 30 where I drop off my car pooler and slept in the Accord. Drove 3.4 miles to his house after a 7-hour nap and nailed a pitiful 31.4 mpg’s :( I was nailed at every other stop light in Joliet, IL. during its own version of rush hour and I was a battling for evcry ounce just to get that!

___At least my total fuel consumption was low but 31.4 mpg’s? I think that is my all time worse segment ever :( Previous 120 miles where at 53.1 however :)

___Good Luck

42 degrees yesterday morning. But, I managed to hit the approach to my first waypoint perfectly - it's an exit that can't be seen when you have to start decelerating, followed by a really tight and somewhat steep downhill turn off. Always feels good to hit the speed right and get to the bottom of the ramp w/o braking!

Even with the low temp, managed to pull off another 64.x mpg 30 mile segment, but playing the "game gage" for all it was worth added another 5 or 10 minutes to the commute. All is for naught on this tank, though. "The Equalizer" drove the car over the weekend, defroster on full blast all the time. Dumped the tank from 61 to 55 mpg. :-(

At least I didn't have to camp out in the car like Wayne. ;-)

Yesterday, got 72mpg on the work communute during a steady rain - could have been worse if I'd been caught in one of the many accidents that morning. Today in the fog got 82mpg. :)

did a road trip last week to southern minnesota, which in total was about 525 miles. i somehow managed to hold a highly presentable 55.4, especially considering the conditions.....snow tires, cold weather, very VERY windy, and the place i went to was about straight up the hill from the hotel, and i made maybe two trips a day. how high? enough so that your ears popped on the way down.

it made me wonder i could ever take my car on a mountain trip? this uphill was only about 4 miles, and getting to the top used up a lot of my battery. i could not physically go any faster in 5th gear than about 45 miles an hour? does that even sound right??? suppose i was trying to get up to the eisenhower tunnel in colorado? what the heck would happen?

after i filled up on the way home, i managed over 60MPG, quite good for mid october.....

yesterday the morning commute was awful......very high winds again..heavy rain...lots of traffic for my rural highway. the trucks going by blew the rain all over, much like they do with snow in the winter. i just wanted to go back home to bed.......

It does sound like that infamous segment of I70 from the outskirts of Denver west 50 miles. I've done it a couple of times and you simply have to downshift to avoid recal. In August, I reset the FCD at I70 and I470, went west 20 miles, then back. Combined mpg was a little over 70mpg - i.e. you could get EPA on your Civic on this killer climb.

If you do go to Colorado, the interstates are a lot harder than the two lanes. On the two lanes, the climbs tend to be a lot shorter. The interstates are more level, but in the Rockies, you could still have a climb of two miles or so, making you very vunerable to recal.

I'm on to G6 #2, as I'm stopping in SC for a side trip (also business) on my way back home. Exact same model, trim, and color as the one I dropped off this morning. However, I now have use of the trip computer since I discovered that it has a MPG function. Looks like the car was just under 30mpg over the prior 300mi or so that it had been driven, and I have it at 33.0mpg since resetting it. It's a bit more of a struggle to bring the numbers up than the Accord but I can't really complain since that was maybe 15 or 20mi tops from a cold engine. So it goes...

I had a relatively average day but I just capped it off with a new personal best for a segment. This morning's trip to the wife's work was 36.4. From there to my work was 56.4. This afternoon's trip back to pick up the wife was 61.7 and from there to my mom's house 11.8 miles away was 58.4. I just got back from taking my daughter to her youth group at church and managed a 60.3 on the way there. On the way home though, I pulled off a 76.8. :woot: :woot: It is a 5.32 mile trip according to Google Earth. The SG only reported 5.1. Looks like I need to do some tweaking. If my calculations are correct, this would have been 80.1 on the SG.

We had bit of a warming trend yesterday with 67 degrees inbound on the commute with a 69.2 mpg / 30 mi segment. Only managed to pull off 67 mpg on the way home when it was 78 degrees? Then had to take the kids out on an errand 6 mi from the house. The Equalizer wanted to use the car today, so I called it quits on the tank and filled up. However on the return trip, I was really happy to see a 84 mpg / 6 mile segment - a new record for the Bond Mobile!

Hi Bob:

___84 mpg out of an HCH-II over a short segment is none to shabby at all!

___Larry, how is the SG-II matching your calculated over an entire tank? Just keep cycling through from the Current, Today’s, Previous Day’s and the Tank will appear. I know you already have cycled through this but just wondering given I find a slight over estimation (1 - 2%) when I do not have a lot of FAS’s through a tank (long distance highway trips) and under estimates (1 - 2% to the low side) when I do.

___Good Luck

WOW the cool temps and wind put it to me this am. 41f, heading straight into a 15 mph head wind. I managed a soild 43 mpg for the segment. Including droping the wife off at her work place. Hope to salvage a little bit this afternoon. Minus picking up the wife. :)

Tanks holding at 45 mpg. What a burden.

The last couple tanks that I checked showed a ~7% underestimation. Unfortunately for me, my SG "lost it's mind" this last tank and all of the data was lost. I went immediately and filled up after it happened and put the tank correction numbers in as best as I remembered. Right now I'm at 192.6 miles and the gauge is still slightly above 3/4 so it looks like it will be awhile until I can see how close the calibrations are. I did find out last night that the SG was under-registering on mileage by 4% when I checked my route with Google Earth. I checked the route this morning that I use to take my wife to work and the SG is right on and the trip odometer in the car was right on as well. It bugs me not knowing whether or not that the SG is right or not so I may just fill up this weekend.
Now, for today's numbers. This morning started out around 52 degrees. The trip to my wife's work was 33.2 due to no FAS so the car would warm up. From there to my work was 60.6. By this afternoon, the temperature had dropped to 43:( and the trip to pick up my wife came in at 58.4. There was also a 5-10 mph headwind. On the way home, the mileage was 56.2 probably due in part to the tailwind.

Finished my time with the G6 today, only at the end realizing that it had a 3.8L V6. That explains the low-end torque! I finished up the 70 miles or so of driving with 32.3mpg showing on the trip computer, which is pretty darn respectable for something with an engine that large driving the wheels through a slushbox.

better work that r18's since i'm getting the same as you :)

Got 85mpg this morning and cheated!

This morning it was 45F in Dallas. For grins I got the engine warmed up before taking it out of the garage.

My work commute:

Total 25 miles = 2 miles residential + 22 miles freeway + 1 mile residential.

If the Insight was not warmed up, FE would have been 75-77mpg.

Most of the winter in Dallas, the road surfaces are clear.

My conclusion: most of my FE loss in the winter is simply getting the engine warmed up the first 2-3 miles.

34f this morning when I left the house and no wind. I was able to ring out 47 mpg for the trip in. This involved droping the wife off and then running over to a cust. of ours and replacing the data plate on a shell and tube heat exchanger, then on into the office. With 4 bars left on the gas gauge I should get home with gas still in the tank. Im figuring 45 mpg for the tank. There is suppose to be a 20 mph south wind this afternoon. If that rings true then Im screwed.

I feel your Civic should do as good as mine. The R18 is a fine engine in its own right. BUT it was a very big screw up on Hondas part not to make it a lean burn IMO. It has more power and the ablitity to get good mpg. And it will go much better than the last gen DX,LX,EX Civics. It will basicly run with the last gen Si Civic (ep3). It is also capible of as good or better mpg. But using its low rpm, low load design is tricky at best. :)

Wayne spiked a soild 80 mpg ave in it on a short drive. But alas that is unuseable driving for me. My daily driving dosent allow me to be on country roads or section line roads. :)

Tank came in at 45 mpg.

Today was rather average for me. This morning's segments were: 32.8 taking the wife to work and 58.4 going from there to my work. This afternoon I saw 59.7 going to pick up my wife and 52.4 from her work to home.

I just got back from filling my tank; it was bugging me about the SG calibration and I couldn't wait.:) The SG said I used 4.7 gallons and had computed 50.8 mpg. My car's odometer registered 238.4 and has been found to be accurate according to Google Earth. The actual numbers were: 4.603 gallons used for an mpg of 51.792 mpg. On the way home from the station, I managed a 76.8 mpg segment. The temperature was ~56F and I had my wife and daughter in the car so there was about, um, 200+ pounds more than usuall.;)

drool! I wish I could pull of those segments.

I forgot the wind conditions. The winds were out of the SW @ 5-10 mph. The first 2 miles of the segment were headed due west. The next 4 miles, I was headed due north. Then the last ~1/4 mile was heading due east. I may have gotten some help from the tailwind.:) It also could be due to the power of plastic body panels. My curb weight is listed as 2390 pounds.

2006 Toyota Prius, 2300 total miles.

I was able to raise my tank average from 72.0 to 74.4 mpg (601 total miles so far) this week over about 180 miles. During a short experiment, I had about an 18 mile segment at about 100 mpg. I averaged near 80 mpg to and from work this week.

I have learned quite a bit during this tank. I have been maximimizing the glide portion of the P&G. I have really minimized battery usage during glides. As a result, the higher SOC during pulses results in higher instantaneous mpg values which makes my glide distances shorter to acheive my goal; 100 mpg.
