I just bought this jeep last week, ive only went 115 miles and im already at 1/2 tank. last tank i only got 9-11 mpg and that was mostly highway, does not seem to spit and sputter or have any loss of power. let me know if anyone has any ideas, also Ive been easy on the throttle. tryn to figure this out before i start the mods.
