Sitting at 11K miles and about 20mpg as of late, which has definitely been nice. Still having to manually add 3-5gal each fill up since it clicks off around 16-17gal when I fill up.

I can't remember who, but I did see a post on the forums stating if you keep your RPMs generally around 1.5-2K you'll see an improvement
Have you tried pulling the pump nozzle out an inch or 2. I notice early shutoffs if I have the pump all the way in, but much less if not.


I started out in the high 19's low 20's, but after changing wheels, I dropped to the 17's and 18's.

I have tried the nozzle trick at different stations, generally helped for maybe a gal or two? Otherwise same issues, thanks though!

Just curious. Who in thos group thimks that the mpg computer is correct? I have a jeep that's not accepted by the JLUR or JLR or any other JL owner.(WK2) With a 3.6. I calculate by dividing miles driven by gallons pu in at click off. My mileage is consistly 2 2 1/2 mpg worse than what the computer says. Which is more accurate? Doing it old school or looking at the mpg on the dash?

Old school is more accurate.

But over the last 7000 miles my computer and my manual calculations have gotten closer, to the point they are within about 0.5-0.7 mpg apart

When I get gas at Costco. If the pump is on the right side of the car, the long reach makes the nozzle slip out a little and shuts down, often. It’s finicky at other pumps as well. I get just over 20 mpg in my mall crawler.

Mine shows a little higher on the computer. It’s usually 1/2 to 1 mpg higher than hand calculated, but it’s reasonably close.

+10k miles with 21.1 mpg (calculated) vs 23 on the display. Mostly urban commute with stock 2 door Rubicon.
I leave the center screen displaying the MPG graph to encourage better mpg.
I have a cool Ap on my phone that tracks every gallon of Premium I've used.
Worst was rock crawling @ 19 mpg LOVE MY TURBO!

25.4 mpg (on display) on my casual Sunday drives. 24.5 on my commute. Driving the 2.0T Sport S stock everything 39 PSI all around.

Calculation average seems to be 21.5 mpg at 418mpg per tank.

Felt the need to show off my 27.1 average on the dash display. I haven’t figured out how this thing averages. It usually is around 23 but bumped up significantly on a +150 mile drive. Stock 2.0L Sahara.

I'm probably only getting about 14 mpg average on a stock JLUR. I drive it pretty hard in the city traffic. It still gives me a big smile I'm sure off-road it gets even worse mileage. Maybe half that. But I will use it for what I bought it for.

So my Rubi on 37's was only getting 16.8 MPG when I had the tires filled to a supple 28psi, I bumped them up to 32psi and my MPG has jumped up to 19.7 still have a good contact patch after chalking but I do get bounced around a little more on the 6 mile stretch of country road I have going to and from work

To get this type of mileage, you have to drive 55-60mph down the highway. Who has time for that???
Doing 75-80 from OKC to Santa Fe and back. I will say on the way back the wind was blowing and it felt like the hand of God was pushing her down the road :)
