Not sure exact, but city is 14ish on short drives and the average climbs to 17-18 on highway. Reading this makes me want gears and I was fairly happy with the 4.10s and 37s.

Pleasantly surprised at my averages so far (just under 2K miles driven). Like many of you, I have checked actual numbers at the pump and they are close, sometimes dead on.

. thought I had a picture of my average but I don’t.Average is 17.9 mpg. I see 20-22 pretty commonly cruising on the highway. It’s the stop and go traffic in town that kills the average.

@wibornz brother I have a whole thread on this!

Spoiler: 17.8 mpg for a stock 2-door, manual transmission, 3.6L Rubicon with mixed driving.

I read your thread, and you are the reason that I stopped using the Auto/Start feature. I started this thread so that we can see the wide spread of milage difference between builds and different drivers. My wife is a god dam maniac. I average about 30% better fuel mileage than her is just about every vehicle we have owned. Drivers can make a huge impact.

I didn't take a picture, though I will next time. I got 26.something on my trip back from Charlotte (to north of Atlanta). That's on the 3.6 in a JLUS mostly stock.

My fuel economy gauge is a liar. It says I'm averaging 19 when hand calculations is closer to 13-14.

hand calculations are 26MPG with 3k miles, but this was the only pic I have. And I have been above this but couldn't take pictures because I was in motion.

Interesting. Mine has never hit the hand calculated MPG, ever. It's consistently 5-8% high (on the dashboard display) vs my hand calculated MPG. Maybe the 2.0 MPG computer is off more than the 3.6 :)

'21 JLUR, 2.0L Turbo, 35" tires on OEM wheels, Mopar lift, winch on front. The pic is from a trip from Scottsdale to Ouray & Telluride including trails. This is the best mpg I've gotten by far.

Hand calculated the last 8 fill ups and MPG for each fill up. I want to see what my average is at 10 fill ups. Mileage has been 2,611.3 miles with 116.4 gallons of gas used.
The computer will show around 24.5-25 mpg but the hand calculated shows 22.4 for the total average of all tank fill ups..


This is from my normal driving habits. Around town with stop and go. Out on the country roads just getting from point A to point B and some interstate.
