I am guessing around 13MPG at least?
My Jeep stock with 3.55s and 30s was getting 13.5 MPG, and now with a broken muffler and RE 3.5" lift I get 11.5 MPG. It hurts.
BTW what part of Florida you in?

If the check engine light is on, that means you're in limp in mode and it will decrease the MPGs. You need a scan tool or a code reader, or cycle the key three times to see what the code is.

Put 410 or 456 gears in and if will fix that. I have a 96 xj with 35 and 456 gear and got 15 to 18 MGP I had some motor mods to.

I just put on 35's and the last tank, I got about 12 MPG. That was mostly highway.
4.56 gears with 35's
My calculation is correct since I also just changed my Speedo gear and the odometer is spot on.
