3200 miles so far, average is 21.5 mpg with a lot of highway miles At 75-80 mph, 35 KO2’s winch and Rock Hard mid-width steel bumper probably doesn’t help.

I have been averaging about 27.7MPG in mostly highway driving in a 2021 Gladiator Overland Ecodiesel. I did manage to get 30.9MPG on a trip to the national forest with some light trail riding and hilly highway driving.

How to kill mpgs. Start with a brick, lift the brick higher in the air, put bigger off road high resistance rollers on the brick... this has happened to every Jeep and truck I have owned. If you value mpgs, don't buy a brick. I think having anything with 'wrangler' on it getting low 20s is amazing.

This was a full day trip to Jeep Adventure Academy at Windrock park outside of Knoxville, TN. Approximately 300 miles and 5-1/2 hours at highway speeds (65-80mph) on very hilly section of I-75 in KY and TN. The other few miles and 4 hours was offroading, crawling, idling, etc. I think the 24.5 mpg is very respectable.

Two weeks ago I took a trip across southern MN, all flat lands at 55-65 mph. 365 miles. I got a tremendous 33 MPG. Then I did another trip fro SD to ND , all flat lands at interstate speeds 75-80 mph. 390 miles averaged 26 mpg. I’m pretty amazed at those numbers.

And you averaged about 75 mph. That's really impressive, even if your trip computer is a little optimistic.
Yea, I set the cruise control for the most.. the computer has been recalibrated to the 37s also, I get a range of 458 miles on tank.. I’ve been very happy with the Diesel so far no problems, I know I’m only at 10k.

2021 Overland diesel, running Falken Wildpeak ATs, 275/65/18s, stock wheels, no lift. Just over 10,200 miles, run 50 miles per weekday to/from work, mostly at about 75. Showing 25.5 mpg on the dial.

Did just run up from Orlando to Charleston and then on to just outside Galveston/Pigeon Forge on vacation. Riding around in the Smokies (not trails). Per the Fillup app, ran 1,769 miles over 9 days, 25.13 MPG.

Mathematically calculated mpg is 25.4 403 when I filled up put in 15.86 I usually fill up in the same manner. Wait till it clicks off then add an extra 1-3 dollars. Mixed driving 55-75 mph mountains some trail/fire road driving and back and forth to work. Can't complain at all.

Here is today’s run. Up over three mountain passes. One at 10,000ft. Mixed speeds 65-40 mph. 3.73 gears on 2021 Rubicon with 2” Mopar lift and 35x12.5 tires. It just keeps getting better. The range is great at around 600 miles per tank

Man, y'all are killing me with these posts. I'm beginning to wonder if mine is defective. LOL. I have only seen 22 mpg once. Averaging about 20 mpg with mixed driving.
Stock except for 35" BFG KM3's, and Tazer Mini to adjust tire size. Granted I only have a little over 1,000 miles on it, so hopefully it will improve as it breaks in.
