My 2002 SE gets about 31 Highway and 29 City. I drive somewhat heavily but when it is nothing but highway i get around 32-34.
I keep speeds at 70-75 on highway and I always try to anticipate stoplights by going into neutral and using the brakes. Last tank, with 15% city driving, using these methods I was at 360 when my gas light came on, since that is 10% remaining that puts it close to 400 miles. Best i've ever done and i'm at 43,000 miles.
