We talked about this a while ago, and although our cars are the same, most of us have different results. My car's 15" steel wheel setup is the lightest, w/5 spd tranny, and in combined cycle driving I get 350 mi before the light comes on.

One cause is variance in wheel sizes- 16's or 17's. Did anyone here switch from factory 16's to factory 17's and noticed any changes? I am afraid that going from 15's to "lightweight" alloy rims will cost me add'l 2-3 gallons per tank.

yeah.. that sounds right.. I have the 15 in steel setup right now and with 100 miles of highway and 250 local.. my light just came on yesterday... about 350 miles. and put about 15 gallon in it.. so that gives me about 23 miles per gallson.. pretty good with mostly local driving..

My car is all stock, but I have not had any problems. Even running it hard I am pulling out about 28-32 MPG. But hey, not given any complaints. Just happy about it. I run 91 and drive it at about 4500-5000 most of the time.

The best I've got was 24.4mpg at 85mph for the whole tank.

I went from the stock 16's to stock 17's and didnt notice any diffrence. The best I've done is 360 miles all highway, I average about 320-330 miles under normal conditions.

Made a run to Fla and didn't fill up until about 415 miles and did a little better on the way back. Don't know how, just did. Running about 95-100 all the way. BUT, I did spend about 40 miles behind a rigg. Only on the way down, not back.

My GXE has the 16" aluminum wheels that come with the convenience package. I always get between 23-27 MPG.
