Stock Rubi
15.5 to 16 daily driving. ( my commute is a mix of side streets and interstate. (17 miles each way to work)
I have a heavy foot, I do not drive for gas mileage.
I did get a little over 22 on the gauge going across Eastern Oregon and Northwest Nevada this summer. But I suspect some of that was the long gradual down hill drive.

As for the gearing, Trail Recon had 5:13s on his Gladiator and had them replaced with 4:88s. He said the 5:13s were too low.

21 Ecodiesel, bone stock I was at 26.8 around town to and from work 18 miles each way. Currently Rubi take off tires and a loaded camper around town 22. Highest I've ever averaged was 35.2 between Flagstaff and Albuquerque. Considering the slight downhill approximately 6ft per mile. Still only burned half a tank. Longer trips with camper still hitting close to 25 on the long highway. Going 2.5 lift here pretty soon.

I’ve been tracking for over 100,000 miles now. Rubicon.

In the month and a half that I have owned it, I have put on it 2865 miles which included a 10 day trip to MA. I'm currently getting 21.5 MPG. My wife had it up to 24.0 MPG until she hit traffic on the way up there, then had 8 days of short around the area trips. 'I'm very happy with that.

Interestingly enough, I find the correlation between the MPG in the dash and the actual calculated MPG to be less than impressive.

It's actually really close over multiple tanks of fuel. So far, mine is within .5 MPG over hand calculations.

In over 100,000 miles of tracking, i have not found mine to be that accurate. And i have tracked all 110,000 miles except about three tanks of fuel. But exactly what is "accurate" is a matter of opinion.

Same here, this is the closest vehicle I've owned regarding actual MPG vs indicated.

My land rover consistently told me I was getting 18 MPG, when in reality it was about 14.2-15 depending on wind speed.

21 Rubicon Diesel, 4.88s, 35's, ESS off. Drive it like I stole it gets me 21mpg. Drive it like a grandpa gets me 23mpg. I'm sure it will increase after the 37's installed as the RPMs will be lower.

I average 14.5-15 mpg around town and about 19 on the interstate. I do not drive to conserve fuel and my JTR is stock including the mud tires

I can average 18 mpg filling up after I get out of my part of town going to and from work but as soon as I start up the hills near my neighborhood my mileage drops quickly to normal mileage for me

15.5- 15.7 mpgs on a 23 Mojave with Nokian 35s, steel front bumper and winch, and tonneau cover. No lift yet. I have 5800 miles on it, so hoping break in mileage starts to improve. Mostly valley driving at 3000 ft.

 

[Bbannongmu]

Update - on 37s with 5.38 gears and 6speed manual. Showing 13.9mpgs on display. Hand calculated to 13.5mpgs. Probably .3 mpg difference from 5.13 gears and stock 4.10 gears on 37s.

 

[TJMarc]

Diesel Sport w/ stock gears
Stock: 26~28 MPG (Hand Calc) depending on driving habits

37” tires, 2.5” lift, stubby bumper, skids, smartcap, ect: 19-21 MPG (Hand Calc) depending on driving habits

I noticed about 1 mpg lost from the SmartCap, 2 mpg lost when I did the winch, bumper, skids then about 5 mpg lost when I did the lift and tires
