I don't have off-road tires or any lift or anything, and I'm getting between 20-22 on the highway. That's with a heavy foot, though.

I used to get 20-22 highway on my 4.7. I just had to do heads and now I seem to be getting 17-18 If I ever recover from the head job and am willing and able to spend 5 minutes under the hood I just might figure out why.

I can get 22mpg but only if I go 50mph, lol, about 17 at 80mph. 65 is a happy medium at 19mpg.

I have the 5.2 with 137k and I get somewhere between 17.5-17.6 for an average. It's probably a bit more city driving than highway. If I ever get a road trip in on the thing I notice averages around the the 20 range.

For those that are noticing a dip in mileage here's something to consider. It may not be your Jeep. It could be the type of fuel you fill it with. If you have a favorite place to fill up and use them on a regular basis, it's possible that their gas is junk. I had this issue recently. I always filled up at the same station every week and began to notice a drop off in mileage and performance. A friend of mine said he noticed the same thing with his truck and said he was going to find a new place to fill up and see if maybe we were just getting bad gas. Turns out, he was on to something. Once I changed gas stations my Jeep had better throttle response and fuel mileage.
