Hey all, I have been using that Fuelly site to get my gas mileage. Im at 12.7 with a combo of city/highway driving. I change my oil regularly and my air filter is clean. What is wrong? I know the lift and all terrain tires are hurting my mpg but this is very bad. Any ideas? Thanks Sam |

It' advertised as getting 16city 17combined, 20 highway. Some of you guys are running much bigger tires, heavy bumpers and winches, much higher lifts...obviously this will drastically decrease mpg. I never followed mine until now and was surprised at how poor it is. I only have a small OME lift and stock size General AT2. I think I should get better. I am going to try the homemade CAI and see if that helps. Also, im probably due for new spark plugs...anything else little i can try? |

I have two Libertys and a Wrangler all three suck in the mpg dept. Even my 7.3 diesel gets crappy milage but that's because of all the performance work I have done to it. |
