In my experience shortening the diff ratio with the 3.6 to 4.10 or somewhere closer to 4.56 wouldn't hurt the highway mpg. And would help the city mpg.
Your personal experience vs. testing many vehicles on the specific test sequences used by the EPA and the auto makers. OK.

Whatever the reason, you have to admit it can feel like we're being short-sheeted by Jeep by not offering lower gears than 4:10 on JTs with 33s when we used to get 4:10s on 32s in the JKs. I know that's simpleton reasoning, but still :)

A large majority - and that's no exaggeration, are fine with the stock gears. Gear changes happen, but not to most Jeeps.
We also have automatics and 8 transmission ratios and a low low ratio in the Rubicon.
I ran Rubicon 33s (which are really only 32.8") on my JT with 3.73 gears and had no problem at all, was fine with it.

See to me that makes sense… but I would imagine most people aren’t built as much as you are… there was a guy on YouTube pretty much a stock Gladiator and he was only getting around 16 and he lives in Texas… (I live in NH)
Stock 23 Mojave(except for 35s), only getting 14 mpg around town. Hope it does a little better when it's broke in, only have 1200 miles on it.

2024 4Runner / 1995 YJ
I find this to be a contradictory take-
The 4Runner is built on 14 year old underpinnings, and it gets worse milage than the Gladiator. It has less breakover, approach, and departure angles. It's well known to have terrible steering, and maybe they fixed it in the '24s, but it's generally considered a bad choice for a DD when Toyota has so many other great offerings.

So, if you're complaints are it isn't big enough to do truck stuff, too long for wheeling, and being a bad daily, it seems like the 4runner is the worst possible choice you could have gone with- you just traded all of your problems with it... for the exact same problems. The folks over at Car and Driver compared the two and came up with the same thoughts.

https://www.caranddriver.com/review...2/2020-jeep-gladiator-vs-2019-toyota-4runner/
Car and Driver also consistently rates the Ridgeline the best midsize pickup; are you really going to give their opinion any credence for anything on the topic?

I'm not going to go any further to justify my purchase other than to say that for my needs it's an upgrade in every way except the one the YJ covers. I could not possibly care less what anyone here or anywhere else thinks otherwise.

Same boat how long does it take?
My 2020 started showing a fair difference around 7-8K as I recall. This one was a bit less.
It's going to vary with how much and how it's driven, of course.
It's not likely to jump 3 or 4 mpg but it will get better.
Of course, winter fuel and winter weather doesn't help any.

Making a general comment that doesn't negate my point and logic in any specific way. Ok


Taller gearing always hurts city mpg. So it will need to yield better highway mpg for the average to even come out even.

3.73 gears with the JT in most situations is too tall and hurts highway mpg. I repeatedly get better highway mpg driving in 5th than 6th at 70 mph, at specific loops I drive consistently over similar weather conditions, both watching instantaneous readings as well as tank averages using 5th or 6th over a tank. That would be equivalent to a 4.20 diff ratio using 6th.


Therefore, if the specific test sequences used by the EPA indicate that 3.73 give better city and highway mpg, then that directly contradicts my actual fuel economy.

Hence my original point.

They don't run 70 mph in the tests.
Mine rarely sees 8th - the system knows what's best in most cases. I can't shift manually and get better mpg here. I tried - and decided to let it shift and saw a bit better averages with it deciding based on torque loading and so on.
I've found that I run great in 8th in much of KS and FL and watch the mpg climb vs other states. It runs the engine in a very efficient band, good power for keeping speed on the flats.

So your 'results' differ from mine, and of course will differ from the testing they care about.
Really we can say - it doesn't matter what YOU see personally in your limited experiences because you don't match the testing at all, or what others, like myself see.

Yeah, where you live. Mine sees 8th a whole lot on runs between here and Colorado, for example. It lives mostly in 8th, same for in much of Florida. 8th gear, mostly stays there, and mpg climbs a lot.
The issue is that everyone will have different experiences -gear for your needs and where you live. None of our driving will be a perfect match for the EPAs test sequences. And that's all that matters. That's my point. Doesn't matter what other OPINIONS are - they have to do what works to pass those specific tests and what's best for the masses.
A stock Overland can not only meet, but beat EPA estimates on mpg - and in some places I've been, stay in 8th gear quite a bit.
For me, the truck is not too much for the 3.6, and although here, I don't see 8th a lot because it's crazy hilly, I do see 8th a lot driving in other states - KS, NE, FL, for example. It stays in 8th and mpg jumps up. I went from 19 to 22 after hitting the area south of Atlanta and all around Florida, and much of the driving was in 8th gear. When my truck was stock, 23 wasn't out of the question.

Totally depends on how you drive and define "city mpg". You have a torque converter. An automatic won't see a lot of difference either way.
In the 70s, cars went to 2.73 gearing for better mpg averages.

Good word for it - it's also "antiquated" and I only appreciate that in my cars and other things I collect.

Highways where you live vs. where my son lives vs. where I live, vs........... I get they need to have some standardized testing, makes total sense, compare all vehicles on the exact same testing, no matter how real or unreal it is compared to the end-owner, but..............

I used to joke with people, especially my wife and her friends when they'd drive to Florida and back when they commented on getting better mpg going TO Florida than coming back home.
I told them - it's because you are driving DOWN to Florida and UP to Iowa, literally, then take prevailing winds into account. They thought I was joking until on a trip to Colorado springs and back I left my JT's display on the off road pages and showed "altitude' and could show here a constant steady drop in elevation all the way back home.
I told her - 'it's all down hill from here' as we drove home.
