Re: 4.56 or 4.88...that is my question.
Simple things to improve gas milage:
remove roof rack bars and offroad lights on the roof (there was a study that this alone can drop your milage by 10%)
remove spare tire
remove extra weight not needed
install k&n air filter and keep it clean
inflate tires to 5%-10% under max air pressure and keep an eye on them
use mobil 1 gas saving fully synthetic oil
put the car in neutral when coming to a stop or going down a hill
With my 08 h2 I can average 13.5-14mpg in the winter and higher in the summer mostly city driving. I can hit 16s on the highway in the summer time. This is different than the older h2s as it has 25% more horsepower and a 6 speed transmission but all these things add up.

Well, I ain't worried about it.... I ordered my Duramax 6.6, allison transmission and transfer case yesterday.
I won't be installing them probably till summer but the quest begins.

Yeah, I'm gonna need it... I seem to be problematic when it comes to conversions and the such.
