I've been travelling a lot lately and haven't been on the forum so here are a few.
The poor thing has been neglected lately but it's still alive.

Fantastic! My first Jeep when I was in high school was a used (really used) '66 Jeepster and after I sold it, bought another one a year later. They were, well, unique. Both of mine had the 231 Buick V6 in them that shook a lot before they figured out how to balance a V6 engine.

UPDATE ON Earlier post

My 2021 JT with 3.6 now consistently gets 22.5-23 mpg. combined back road and interstate @80 mph. But the Brick TJ only 15-16 mpg.

I have owned five different Jeeps so far in my life.
1) 1985 CJ 7 with a 4.2l inline 6 cylinder, 3 speed automatic, 2“ shackle lift and 32” tires
2) 1995 YJ with a 2.5l 4 cylinder, 5 speed manual, stock suspension 32” tires
3) 1999 XJ 4x4 with a 4.0l inline 6 cylinder, 3 speed with OD, stock suspension and 32” tires
4) 1998 TJ with a 4.0l inline 6 cylinder, 5 speed manual, 4” lift and 33” tires
5) 2021 JT Mojave with a 3.6 V6, 8 speed automatic, stock suspension and 33” tires

I was driving my JT today and looked at my gauge cluster, I noticed I was averaging 19 mpg. Not that this surprised me as I always seem to get high 18‘s to mid 19‘s with the JT.
The thought occurred to me that every Jeep I have owned has gotten right at 19 mpg.

Seems to me the engineers at Jeep have this hard set rule for what kind of fuel mileage their products should be getting.

Just some random thoughts as I was doing windshield time today. 🙂
19mpg? Man, I wish I could get 19. That said, mine has been going up a little since summer started and I'm off work (~2 - 4 mile round trip). I think I'm at around 15mpg now.

3.6, auto, sport with altitude package on 33s and 2 inch lift

Do you drive downhill with a tailwind everywhere you go?
Maybe he has his system set for kilometers instead of miles. So he's getting about 13 mpg.

I am getting 23 to 24 with my '26 Sport. It is pure stock and I don't have a heavy foot. The Pentastar Durango we had did about the same.
