A corny as this may be, I've always had small cars as my vehicles. This is my first SUV based car, and I know gas mileage is significantly worse. I don't do any highway driving, and decided to check what my gas mileage was. (I always leave it on the temperature gauge) it was at 20.0 mpg! I feel like that may be good for city driving in a jeep. What kind of gas mileage do you guys get?
