The only thing you can really do is drive like an old lady. No offense to the ole ladies out there. Ya got a 3,000 pound un-aerodynamic brick being moved around by a 150hp 4 cylinder and it takes gas to do it. The more times you stop, the more gas it takes to get going again. Tread lightly on the throttle and you can improve on 20 - 23mpg but the people behind you won't like it.
