I've been getting 16.3 for the last two weeks doing almost exclusively city driving.
I have 35x12.50r17 Yokohama Geolandar X-ATs and the Teraflex 1.5 inch level as well as having trimmed the front air dams on my sport.
Only down about half a mile per gallon from the FCA numbers so I'm satisfied.

I get around 16.5 mpg mixed city and highway but mostly highway. I have an LE and live in Seattle so it’s hilly but it’s bounced between 15-16.5 mpg so far

I would consider giving half a testicle for that mileage on my STOCK jtr.

I am sitting at 13-15 MPG's, Rubicon specs, 33" wheels, no additional lift. Envious of everyone sitting at 18+ MPG's. I have about 2600 miles on it. Not sure why my MPG's are so much lower than most of you.
Im at about 10,000 miles now, stock rubicon, 35psi

I am seeing 17.5 - 17.8 consistently with colder weather
Was at 18+ in the warmer temps.

I have noticed that the more I drive on the highway the lower the MPG's

My driving is mostly city, probably 80%

Took at look at AVG MPG today.. Two days of city driving in Charlotte after picking JTR up at dealer...then 9hr interstate trip home...then just over a week of city driving...too and from work...too lunch, etc...16.7. About 1200 mi on still stock JTR w/MTs. Considering my 2dr 08 JK was getting me 11-12mg with a good tail wind...i am happy =P

This weekend I need to adjust tire PSI w/chalk...Dealer put them at 41 which I think is too high.

My stock JTR got about 16.5 city, and around 19-20 freeway at 70-75mph. Stock on 37s I dropped about 1 mpg in both(calibrated with Tazer and verified at the pump).
Now Lifted 3" with 37" Yokohama MTs I'm sitting at about 14.5-15.5 city now. Havent done enough highway driving to get an accurate number there yet. This is Northern NV high desert and Eastern Sierra mountain terrain.

Mine is similar to yours. Stock Rubi, part highway driving, part interstate. The colder days it drops into the 17's, and warmer days, I have gotten up to 18.8

Rubicon LE with stock wheels and 35" Wildpeak AT3Ws, Warn winch and mounting plate, Tazer to recalibrate, everything else is stock

So I've found this to be extremely varying based on the type of driving and where the driving is. My daily commute is about 8 miles not on highway, 32 on highway at 72 MPH, and I've seen the instant as high as 22-24, but can't ever get the average out of the mid 17's tops, usually more in the mid 16's. Last week I went on a road trip over varying terrain, but 99.9% 72 MPH highway and it was regularly getting in the mid 18's for average for the part I wasn't towing a trailer. Same speed, similar terrain variance to my normal commute, but much longer highway stretches.Now coming back pulling a 2200 pound trailer (12.5-14.5) was a different story, lol

My all stock Sport S auto is showing 19.3 mpg now half way through the tank. Last tank ended with a reading of 18.5 mpg. I drive reasonably and am never in a hurry to get anywhere though. I drive 45-50mph just about everywhere around home and highways I do 60-65mph. I probably piss people off more than anything even though I do the speed limit lol Folks need to chill out and enjoy life.:sun:

Exactly my situation/driving and resulting mpgs. Though I have 350lbs of sand in the back and about 100lbs of gear under the seats.

2020 JTR
Jeep Gladiator JT owners post your MPG CB7C804A-5A5F-4226-9BE5-7C93CC473DD4
Been averaging just under 15. JTR with 4:10’s and stock wildpeak m/t’s. Of course I did put the terraflex 1.5” spacers on the front, daystar 3/4” spacer in the rear, And high clearance bumper with 15k winch on the front in the first week. Bought 12/31/19. Last fillup was this morning. Don’t remember exact weight on the front bumper or winch but the 1.5” spacer netted me a rise of 5/8” in the front after installing all of it. Gained 3/4” rear. Wanted small lift to keep the 35’s I have for off-roading from stuffing but stay low enough it will fit in the garage. Also wanted to keep factory rake so I wouldn’t be nose up towing the camper. As others have stated, I’ve noticed the biggest difference with various speeds. Filled the tank and reset then drove around town running errands and dash showed 10 when I got on the highway. Another tank fill was straight to the interstate and it showed 19.X when I got off (running steady 60-65 in traffic) another time, same gas station same stretch of road, running late to work showed 13 at exit having run about 80. One short trip towing the 3700lb trailer, reset before leaving the house, dash showed 9 when I got back home. I’ve also had 5 long sand bags in the bed for a few of these weeks as well.

I’m sure if I could keep my foot out of it I’d probably get better mileage but this one seems to have a pretty good growl to it when I’m in a hurry or apply more skinny pedal. :LOL:

Honda Ridgeline. Gator Gladiator Rubicon
Stock Rubicon with 2000 miles and I get 17mpg. My previous truck (AWD Honda Ridgeline) I got 22mpg. Both trucks being driven the same and going the same routes.

My only complaint with this truck is the fuel tank capacity. I think it is ridiculous I can't even get 300miles out of a tank of gas. I can't remember the last vehicle I owned that got less then 350 miles before the gas light comes on.
