thgr8alex Hmm.. I get about 16 but thats to be expected with 5 in lift and 33x12.5s. But i wonder if it would get better with new plugs...

01tj-Bob If the plugs were that bad just think what the Tranny and Dif fluids must look like. Time to get busy!

what a diffence!!!!

When I first bought my jeep about a month ago, my gas mileage was horrible. Looking online it said I should be getting somewhere around 18mpg but I was getting 15 at best. I pulled the spark plugs and they looked like they had never been changed. The electrodes were burnt down to almost nothing. I replaced them and just for s&g's I replaced the cap and rotor too. The last 2 tanks have both come in at 19 and 20 mpg. Big difference. I'm gonna go over the rest of the engine because if the PO neglected something as easy as spark plugs, who knows what else needs to be replaced.
