You just have to drive like you're a little old lady  . I'll be taking the spoiler off next week, as it's the only reason I can think of to explain why my SE-R's mileage drops like a stone at higher speeds compared to my wife's '06 Hyundai Elantra. Their final gearing, Cd, weight, and frontal area are similar. The Cd probably came from some Nissan PR handout, so it's the most likely suspect.
