Wow 22mpg , I'm lucky to get 12-15 and all I got are some 31's on it. I'm changing the axles from 3.07 to 3.55 in the near future hopfully I get a couple miles back. I'm not complaining I get on it once and a while, but the highway sucks it down fast it bogs down at 65 70mph especially when I got a head wind or going up a hill it kills it, I loose mph's fast. I try to draft people to help it some.
