Gas mileage

[tyler1bo]

This may be a really dumb question, but is any H2 owners actually getting decent gas mileage? I realize adding wheels and tires will affect it but I'm just curious as to what everybody else had.

Thanks

37" tires, 4.56 gears, aftermarket headers/exhaust, performance tune: 11.3 in winter, 11.7 in summer.

It was about the same when it was stock.

I think I just need a few performance parts so it doesn't have to work so hard. It sucks that GM put this massive engine in this extremely heavy ride and it has hardly any horsepower, as opposed to what it could really produce.

2005, 37" tires, 6 inch fabtech lift, cold air intake, superflow exhaust, 10.2 mpg

I looked at mine today..exactly 10.2 mpg. And yours has a six inch lift with 37's! Man I'm getting ripped here.

Stock tires and exhaust, 12.7 mpg mixed city/highway driving.

What kind of exhaust? And that's not too bad right there, I would take 12.7 easily!
