My Mojave wandered so bad at interstate speeds I thought I was going to die on the drive home from the dealer after buying it. Swapping out the shitty Falken MTs for 35 KO2s completely fixed the issue.

Regarding engines, it's not that the 3.6 is bad, it just the JT could be so much more fun to drive with something better. I briefly owned a Willys XR with the 4:56 gears and the 2.0L engine, and the thing was a blast to drive while feeling solid as a rock on the interstate.

Just my 2 cents that all stock JT 3.6 models with 33" tires should come with the 4:56 gears, and the models with smaller tires should have 4:10s. And 4:88 should be optional on the Rubicon and Mojave JTs.
I despised the A/T Falkens I had. Terrible ride, poor wear (even with a proper alignment), loud, and bad MPGs. My ride quality and MPGs are substantially better with KO2’s, and they’re even taller than the Falkens.

So, if any of you have Falkens on from factory and have a poor ride, maybe try a C rated KO2. It made my 2.5 inch lift with stiff coils drive like an Escalade (not an exaggeration)

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.

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.
