I think mines sitting at around 26 right now.

It was about 23-25 this winter (very cold), but in the summer I usually get 30-33 (math calculated).

I take off around 2.5k-3k RPM, and I do get on it sometimes. I have a hill to climb when I turn out of work, and then another one after I turn at the light. So depending on traffic, I sometimes wind it up to 4, sometimes even go WOT.

my normal punk kid driving habits, in city, getting about 300-320 per tank with a 2.2 auto.

Highway, cross country, with the car loaded down pulling 390-400 miles per tank

If I baby it, in city probably worth another 30 miles on the first number so 330-350 per tank. dont know what it can do unloaded on a long highway trip. Probably close to the 400 number. thats still being slightly hard on it, no cruise control either.

All in all happy with it, basically hangs between 25-30 mpg

WOT in an XFE? Doesn't it defeat the purpose to get an XFE if your WOT every chance you get?

You should have bought a used LSJ or LNF!

I see 31 in the city, and between 37 and 42 highway, depending on my cruising speed. I see 37.8 driving at 80 mph. BennyHHR did my tuning for me.

I average in the mid to high 20s but all of my driving is highway and its 5 miles to and 5 miles from work. I peaked 36.4 mpg though on a trip down the LIE out to Nesconset. Avg speed was 52 mph for the trip but I was easily booking 75/80 for a large portion of the trip, windows down, no cruise control, locked into fifth gear just cruising.

2.0 lnf Cobalt

On an uphill 340 mile trip to upstate NY this weekend I managed 30.1mpg while doing 70mph. I'd say 90% of it was highway.

Going back home and doing 80mph for most of the way while hitting some traffic....28.9mpg

*edit* this is not my normal average. My daily commute is a mix of highway and stop and go...24-25mpg
