I tried changing my driving style in my 03 accord 4 cyl. Trying not to pass 2000 rpm while accelerating and not passing 3000 rpm on the highways and increased my mpg to 250-260 miles for my whole tank...sounds right, the majority of those miles are city. Does that sound right? I'm in nyc and I took the car to the dealer and they said everything was fine and that their was nothing they could do. So I switched up my style and there you go....is 250-260 miles for the tank better??
