Its all dependent on driving behavior. I find that i get worse mileage if i'm in normal and driving aggressively because i'm constantly downshifting and making the car jump from 8th gear to a lower gear takes a toll on mileage. If i'm in sport, it keeps the revs a little higher so i'm not constantly downshifting so i'm finding it gets a little better mileage. My philosophy is that I bought a sports sedan to really drive the hell out of it...i couldn't care less about my gas costs. If i drive conservatively, i get 20mpg...if i beat the hell out of it, i get about 18mpg. The 2mpg is worth the smile on my face
