I get very low 20's on mpg, but I run 75-80 alot when on the highway to keep up. Plus a mix of city driving. But I would say it's 70%HYWY vs 30%City.
My dad was getting 25+ in it before I bought it off of him, but he lives in the country & he drives like a "Farmer Brown"

Maybe I should endeavor to be more like my dad in this aspect...
