I have a 2005 Jeep Grand Cherokee 4×4 V6 and my mileage per gallon is usually around 13 miles per gallon. What can I do to improve this number? When I purchased the car it was averaging 17 or 18 MPG. Now its averaging 13 (which is completely ridiculous).

I really would like to know what everyone is getting for Miles Per Gallon for this vehicle. I know the manual gets better gas mileage, but I really need feedback on the automatic, in city and on the highway with the freedom I package. Thanks so much.

Hello, Okay I got a 2002 supercrew and I dont want to get rid of it but right now its wasting too much gas maybe 16-17 MPG which sucks I want to maybe get atleast 20 MPG what would be the best way to reach that? The truck is 4×4 lift kit and big tires [...]
