I usually get around 28-30mpg on a stock 96 2 door Tracker with the 16v after I make up for the difference in tire sizes.

do you do anything else than what you mentioned?
(because 28-30 is pretty good)

Not really, but most of my travelling is at 2-30 or 50-60.  I also keep the RPM's under 4K for the most part, it doesn't need very much reving.

I just had a 2" installed from the cat back last night, so I'm hoping to get the milage a little higher now that the engine can breath better.
