For the past two weeks I've been averaging 19.2 MPG on my work commutes. This is an increase from about 17 MPG. I actually thought there was something wrong with my gas guage because I'm use to it reading 1/2 full at 150-160 miles and now I'm suddenly going 190-200 miles at 1/2 tank. The only thing that has changed is that I removed my tire from the back, but I can't imagine it would make that much of a difference. Weird! One of my Xterra mysteries I guess!
