Other then a compass or a patriot, jeeps werent made to get good fuel mileage. If you bought one, thinking its going to get 30mpg... well your bad,lol. Mine gets around 20ish mpg on the hwy, and of course less in town. Thats pretty decent for a truck based suv. I dont know if you will find a comparable suv, including the old xj, that got that good of mileage.
