I do wish for a bigger gas tank.

If you’re worried about gas mileage you probably shouldn’t buy a gladiator. if mine needs gas I just fill it up and go until I need gas again. I got for the fun and the looks it get and not the gas mileage

Take the beach with you! I like it!!

After I slid going onto a highway ramp at mild speed with slightly wet blacktop I decided I needed the weight for traction. Hasnt been a problem since. 100lbs wasnt enough, so I went with more. I guess just sand isnt a good description. It is a mix of sand and fine gravel to double up as traction on slick surfaces

19.6 combined, 4.10, 8 speed auto, 245/75/17, All Stock. I 95 stop and go 26 miles PM, Clear 30 minute 26 mile Am ride. Got 24 MPG on 7 day road trip in Octobers.

That may be true but many of us like to control and moderate our expenses across a lot of hobby and needs and a little attention to MPG can leave some funds for other things.

This stock 4.10 - 8 speed at 19.6 combined and 23-24 highway road trip will take a lift and 35s better then any Wrangler before it. Yes I will loose some MPG but I bet I end up ahead of the 2005 TJL and maybe even the 2013 F!50 302-V8. Great JT! and great MPG configuration.

I have magnaflow exhaust, afe CAI, 20" wheels and 35" BFG AT tires...I drive with a brick on the pedal...all together over the first 1000 miles, I'm at 13.7 mpg. But, damn it's really fun to drive in the manual shifter auto

I agree, but I use it to save fuel, it's really flat down here on the coast, you can usually sit a gear higher than the transmission wants to on its own.

Any vehicle is gonna vary in real world mileage according to driver input and road conditions. When you add to that a vehicle that is so easily modified with such wide variations, no two are going to be the same. Having lifted mine (albeit only a small amount) and changing the bumper and adding a heavy winch changes the load bias to be more front heavy and killed some of the aerodynamics so now cruising 50 or so it shows 22+ on the current mileage display but drops trying to push that sail through the wind at higher interstate speeds. Not having the bumper or winch would help, bigger tires or different tires would change it too. Some tires have better rolling resistance than others, 12.5” wide tires sticking out catch more air, and so on. Terrain varies so much by region as well that comparing mine to one with the exact same setup driven by someone else who is less aggressive on the pedal, that is in a flatter state would not be a fair comparison either.
In the end, there is no comparison between what mine, or yours, or his, or hers is getting because there are just too many variables to read two numbers and say “why is mine better” or not as good.

To save fuel, you'd generally want to be in a HIGH gear, not a gear lower than the auto transmission would choose on its own. It chooses based on economy - to keep it in the most efficient RPM range for economy without lugging it. So if you are manually choosing a lower gear, you are defeating the purpose. You are increasing the RPM, increasing the amount of fuel used to accomplish the same distance traveled.
There are exceptions, of course, working an engine hard to the point that it uses more fuel to accomplish the task, but these are programmed to avoid that. They'll downshift before getting to that point.

You nailed it.
Anyone ever wonder why cars have the undersides lined with slick, smooth liners? Why the suspension and under-carriage no longer shows to the eyes? Why you can't lean down under the front and see the lower control arms and front cross-member? They catch AIR. The fronts of the tires catch air (thus the air dams on the sport JT - wish the Overland had 'em)
Popular Mechanics years ago took a Pinto and raised the MPG by a pretty good number by using ground effects, air dams and so on, preventing air from getting under the vehicle.
These trucks sit high, any mods change them more than almost any other vehicle. You can put any driver in the same vehicle and get very different results.
Number comparison is fun, but that's where it ends.
We can compare notes to help others get better MPG - but there's no guarantee of results. Certain rules always apply to help do better, but better may mean an increase of .5 for one person and .8 for another.

Meant a higher gear, did a little typo.

Personally, I'm looking at it this way -- my JT is getting ~20% worse gas mileage than my old Miata, but the cost difference in the 87 octane vs the 93 around here that I had to put in the Miata is like ~20-30% so I may actually be coming out ahead on gas costs on a good day!

So, 1st tank of gas: 14.5 avg. Second tank of gas: 15.5, and right now, it's about 17 avg. Sport-S max tow completely stock, only has around 450 miles on it so far....

That's funny!
On your third tank at 300 miles lol

I was wondering the same thing. I'm at just under 300 miles and am at the end of my first tank. It had around 60 miles on it when I got it from dealership. How are you on third tank at 300 miles?
