One thing nobody has mentioned is brakes. Check your brakes and make sure you don't have a stuck caliper. It's happend to me before. But it also told me it was stuck by warping the rotor. And it was a PITA to get off!! If you got a caliper thats draggin, it'll pull your mpg's down a bit.

Another thing that gets a lot of people another 1 mpg or so is switchin to synthetic fluids. There's been tons of threads about it, but tons of people say that once they switched over all their fluids to syn, they gained about 1 mpg. Its not much, but it'd be piece of mind, and longer change intervals too, which save $$ in the long run.
