If your serious, you can do a few things:
1. Tires - less rolling resistance = more MPG. Ditch your BFG MT's for BFG AT's or even a road tire like Goodyear SRA's. It's a give and take between off road capability and fuel efficiency.
2. Replace your front air dam if removed. If you don't have one I'm certain that you can get one from a forum member for the price of a six pack. [emoji481]
3. Keep the oil fresh and engine in tune. Make sure your oil is the right viscosity.
Those are the simple things. Other things can be done, but the payback will be stretched beyond reasonable limits. Good luck!

I got 20-22 out of the 08 X model we use to have. It was the 3.8 and six speed standard with stock 3.21 gears. That was running the stock size tires.
Once I went to the 285 BFG ATs it dropped to 18 at best.

Same set up with mine and same mpg for stock and lift. In the hilly areas I get less, avg around 16.3 mpg. 4.5" lift and I drive it like a granny in town but like Jeff Gordon on the highway[emoji2]

14.4 average and that's after a year of tracking with an app at every fill up. I don't actually care, I'm just a data nerd. When anyone asks I tell em 60 smiles a gallon.

The biggest bump in mpg I saw was with my programmer. But really only talking about 1-2 mpg at the very best. But my tranny started acting weird with the program, so I re-flashed back to stock program. Right now I'm averaging 15ish.
A jeep has the aerodynamics of brick! Keep up on your maintenance and enjoy the ride. Switch your DIC to outside temp and don't worry about it.

Lol! That's what I was thinking
The Manual transmission must be the secret sauce! I ran 3.73 gears with BFG 35s, auto transmission. Even corrected with a ProCal I was getting 13.5 at best.

My way to work is 25 miles one way and not any stop and go traffic, I also don't use the cruise control. It has been less but the last few tanks run 16.5 and have got 17.5 recently. But my commute is hilly and I coast when going down hill.
Now I normally don't get that in the winter, and if it's windy I get less.

I will also say I have a drop in K&N, and a magnaflow muffler. But I did that mostly for Maintance on the air filter and for clearance on the muffler. I never planned on that stuff saving me and MPG and don't know if it really has any effect on it.

Nope, I say staying light on the skinny petal helps the most, that and my commute is no stop and go traffic.

Always go downhill with the wind.
Seriously though. I get 17-18 in town and 22-24 hwy but I probably have different driving conditions. My Jeep is a 2012 JKU Sport hardtop with 3.73. I still have the stock SRA tires. They are lighter than the BFG Rubicon tire and have less rolling resistance. I live in FL. We have to go to an interstate overpass to find a hill. I am also 40 years old and don't get in a hurry. I enjoy driving my Jeep so I tend to mosey around.
