mileage going up
I am a newbie, and have some news to report on my last tank, which would be the first official tank since signing up with gassavers.
Since reading though alot of threads I have started experimenting with engine off coasting. Wow what fun.
Last night I drove up the mountain pass for some night skiing. Before I left my tank was 1/4 full and the trip is 190 miles. Generally I would fill the tank. But last night I put my new knowledge to the test. Using a new found route (slower - less traffic - hills to coast) and armed with engine off coasting I head out. I note each fuel station carefully this time thinking I would have to stop on the way home in the middle of the night. But in the darkness and on a empty highway I coast like a madman and get all the way home, and the low fuel light does not even show!!! I fill up and note a 32 mpg tank. One of the this cars best tanks ever!!! What fun!!

Isn't it great  ? My favorite thing to do is the pulse and glide. It works better for me in the hi-density traffic of LA and has made the biggest difference.
How many gallons do you have in your car at 1/4 tank? I am wondering what your MPG was for the 190 mile segment.

Great work BeeUU! If you live in a colder climate like where I'm at, when the weather gets warmer that may go up even more.
Temps were 5F this morning. By the time I got to work the SG was showing an average of 46.1 for the 15.4 mile trip. I was able to break into the 50 mpg range this morning on one of the legs.:woot: This afternoon, the temp was ~20F and I had 52.3 for both legs of the commute and the average for the whole day was at 48.7.

I wish I knew. I think the tank was only "OK" untill the ski trip. Coasting down the hill was a great boost for that tank. Although the all the enigne off coasting with the headlights on is hard on the battery!! It was a very quiet night so I had the road to myself to experiment. I did find a new road to get past a lot of afternoon traffic. That was a boost for mileage too. I did realize the additional aero mods are required. Even on the steepest hills the car was slowing to around 50.

Well, after killing the battery the other evening, my trip today was decidedly less aggressive with the whole ICE-offness.
The result: where I could typically pull a low 60 mpg (US) rabbit out of the hat, I was only able find 51 mpg this morning. Typically cold (-18c), snow covered roads. I did a little ICE off, but mostly i left it idling where I would have otherwise killed it.

I had an incredibly bad FE day. Got stuck on the interstate where there was a bad wreck(hopefully no one was injured seriously) and they had the highway shutdown. By the time I got off of it and with all the other traffic diverting to alternate route it was pretty much a killer. I think this is the first time that every light I came to was red. It turned a 40 MPG tank into a mid 30's tank without much hope of bring this tank up to something reasonable. Tomorrow I have a 100 mile road trip, mostly highway, hopefully that will get it going back the right direction. It amazing how one bad day can ruin a whole tank.

Poor FE day here too.  Temps were ~15F with winds 10-15 mph. Today's commute of 31.2 miles ended up at 44.4 mpg.

Well, on a more upbeat note, I finally get this pulse-N-glide thing. I've read many times that it's great for FE, but never understood why. I did two long trips last week and had a chance to work it out in a way that makes sense to me. Then I tried it on some of the hills along the way. I think it works! I managed to get good FE at 38.9mpg despite slightly higher cruising speeds and 5 runs down the drag strip. BTW my new FE logger recorded peak consumption at the track at just over 40.8 GPH! Lukily it was only for a few seconds. whew
