I've got 3,125 miles on mine. My usual driving is a mix of city and interstate. I'm getting right at 23mpg. And I still like sticking my foot in it to hear the pipes in first and second gear. I did take a long intersate trip about 1,000 miles ago and I got 27.2 mgp highway. I'm happy as can be. Much better mileage than I get with my 4.0l Explorer.
