I recently bought a 94 Grand Cherokee Laredo with a 5.2L and full time 4wd. Gas mileage has been 13 mpg the last three tanks. Is this normal? The engine runs smoothly and the air filter looks brand new.
I have a 5.9 with 6 inche and 35s, intake , exhaust, superchip, and intake in my truck and I get 10. I do drive a little heavy on the pedal and around town alot . My last truck got 9 so I'd be happy with 13 . Seems normal to me. Lift , tires, exhaust, age, Intake and so on all take away gas milage but they sure do run good huh? specs seem to be a little over done on most cars but modify them then the specs do'nt count anymore
