Ours is my wife's dd and she averages around 22 mpg, about 50/50 rush hour traffic on the highway and local roads. 2020 Recon 2.0T with eTorque and mostly factory stock everything. She never resets the screen so this pic I just took is from at least 2 months worth of driving since I last reset it.

My best tank was 18.9 according to the lieometer. That was all highway completely stock. Now I usually get 14.5-16 with the 37s.

That on-screen MPG is probably wrong too. Mine is about 1.5-2.0 MPG optimistic vs a hand calculation. If it says 22.5, it's more like 21 when hand calculated. I have had it show 30MPG on a highway drive, was more like 27 when hand calculated which still isn't bad, but the trip computer is optimistic.

431 miles in and 24 MPG so far. Not horrible.

When I used to top off the tank with an additional 1/2 gallon or more after it clicked off, the screen on my GC was usually close to 1 mpg or so optimistic from my actual calculation. After I stopped doing that, the screen has usually been within 0.1 mpg of my calculated result. I suspect our JL would be the same and my wife does not top off the tank when she fills it.

Mine has been this way through 35 fill-ups. I generally stop at the first click. Over 10,000 miles any over/under fill would be negated I'd think, and I have never once had the computer show less MPG than my hand calculated results. I just figure that whatever it says is about 1.5MPG higher than reality.

Every car I've owned with an MPG calculation has been the same way, optimistic by 7-10%. The only one that was generally within 0.1 MPG plus or minus, was my 2014 BMW 320i. It was very close to the hand calculated numbers.

I've been getting pretty low MPG.

2021 JLUR
Factory MT tires (Falken Wildpeaks 285/70/17)
36~37PSI

I installed a Tazer and found that my tire size is set to 33.25"
I have measured all 4 tires. 3 of them are 32" exactly and 1 is 32.25"

Did an experiment today to see if I changed tire size on Tazer what would be the result:

BEFORE (13.7MPG overall and matches my Trip A):
Jeep Wrangler JL 2.0 owners, what MPG are you averaging? IMG_0333

Jeep Wrangler JL 2.0 owners, what MPG are you averaging? IMG_0339


AFTER (17.9MPG for 179miles):
Jeep Wrangler JL 2.0 owners, what MPG are you averaging? IMG_0337

Jeep Wrangler JL 2.0 owners, what MPG are you averaging? 9999000


I know this is hardly conclusive, but it really got me wondering about the factory tire size setting and why it would be larger than 33".

I got two questions.

How did you add the jeep in the dashboard and how did you add the tire ratio?

'18 JLR 2.0
I rented a Bikini 2-door sport in Hawaii where the fastest speed limit is 50 MPH. It got 28 MPG and could likely get better if I wasn't "testing" it as much (comparing to my JLR). At one point I filled the tank and saw a 450 mile range... this is with the 2019+ smaller gas tank.
