Not a 3.8 or a 3.6 but I got the good old 4.0 with 180k with not problems and almost no oil burning.

352,000 miles. Yep. that is a correct #. 1 timing chain, 1 water pump and ran synthetic after the first 50K. However even though I drive to much I just sprung for a new motor. (rear main is leaking now) I am also the guy that gets 60+ K out of my Toyo MT 35x12.5x17 like clockwork. Also decided to up to the 37s this fall. 08 unlimited X 3.8L yes I have hit Moab & the Rubicon and 15 states.:daydream:

66k and going hard
I think I got this jeep with 63 or 64k miles

My 2 door had about 69k and I had to reseal the rear main seal
And I had a noisy engine but that's normal in the JKs I believe

OK, my 2012 isn't a high miler with 43k, but just for grins I decided to see if it could go 5k between oil changes witout adding oil and checking the level often. It used less than 1/2 qt. I think it's gonna go 200k+ mi. if I keep it that long and if I don't beat it up too badly.

Mine is a '12 with 52,xxx. I'm not using any noticeable oil in 7500 miles between changes.
