JT owners post your MPG

[BlckJT]

Ran through another tank. 16.5 MPG, manually calculated. I had about 80 miles of 55 mph highway on this tank. During that stretch, MPG according to the computer was about 19. I am not heavy on the pedal, but i do live in a fairly hilly area. My 2010 Nissan Frontier crew cab 4wd got about 17, so this is pretty similar.

The OP is in Michigan where it’s basically non hilly. Helps the mpg a lot. Lol.

After hundreds of thousands of miles logged in Fuelly.com from real world fill-ups, the JL owners are reporting an overall average of 17 MPG with the 2.0L and 18 MPG with the 3.6L. So I would expect the JT Gladiator to fall somewhere in the 17.5 MPG ballpark after everything settles, considering that it's basically identical to JL but with a little more weight.

Another fill up 17.9 MPG this time (calculated).

The difference is i did about 150 miles on the highway.

I am not sure of my mpg, I retrieved my 116 trailer out of 5 year storage and a lot of tests on the road. I have as of now 16.2 mpg per mile

18.5 so far in my rubi. Jlur got 20.5. I'll give it a full tank or two to see where it ends up.

Im getting an average of 14-16 on my Rubicon 6 speed. All city driving mainly.

with 7000km/4400miles on the odometer my jeep is saying 13.2L/100km for the lifetime average, that works out to 17.8 US MPG or 21 Imperial MPG when using an online calculator. I never know which you are all using living in the USA? This is really mostly hwy or slower country roads, small town driving, and some city mixed in.

Pretty much exactly the same here. 14-16 with Rubicon 6 spd.

Looks like that was right on the money, though with my tires and winch bumper I've ended up closer to 16.0 MPG over 12,000 miles.

15000 miles in this chart. Rubicon. Pretty much stock.

 

[shrinkhead]

16 MPG on stock Rubicon with the AT tires with lots of highway miles. The truck seems to eat into gas once you go over 70MPH and when you maintain that speed going uphill with the ACC. I drive it very laid back so no clue how folks are getting more than 16
