Gas mileage

Hey all, I was just wanting to see how my Jeep compares to others on gas mileage. Ive heard some people on other posts say they get good mileage. Mine, not so good! Last I checked it was getting 12.9 mpg. I have a 4" lift, 33" tires, ram air intake, banks headers and exhaust. Is that about right? Or is there some things I can do to improve it, fuel filter, etc.?

Im not to familiar with the mmo, what do u use it on? Mix it with the oil? And I bought the jeep a few months ago. Already had a oil change. The spark plug wires looked new so I didn't mess with that.

Is your speedo correct. If its not your odo will be off. Mines off a ton and makes it impossible to calculate exact mileage but I get around 15 town 17 highway.

On the highway, anything over 55mph starts reducing the mpg's as fast as the mph goes up!!

Yep. Keep it slow and steady. Honestly a lot of performance parts can actually hurt performance. These babies run pretty great in stock form. I don't know anything about anything you listed however.
