mine gets near 18-20mpg.it's a 2dr & there is a MAJOR weight difference between the 4dr.my mom has the 4 door & it feels twice as big & gets much worse mileage.i got a tornado for mine & i noticed a difference,but ONLY when used in cunjuntion with a K & N air filter.i switched to E3 sparkplugs too.next a cat-back exhaust & flex-fan to replace the weighty clutch fan & numbers should improve again.small things used together will get you better numbers man.
