Just had my oil changed with 0w20. Since I doubt this is a truck I will keep past warranty, I figured I will just go with what Jeep says to put in. I change my oil every 5K miles. I did it at 4K miles this time because I'm about to go on a trip and I'm at the end of the last oil change so I figured I would do it 1K miles early as opposed to after the 5K mile mark. Now my OCD is all messed up because I was on the every 5K mile mark and now I have 9K miles on the truck. Oh well I have fresh oil and filter with newly rotated tires.

I am sure people will say i am wasting my money, or that i am ruining my vehicle. But, my 2018 JLUR went 156k miles without any engine issues (aside from the filter housing).

My 2023 Gladiator Mojave is at 40k trouble free miles too..

I run 5w30 full synthetic and change it every 3k miles. I add in zddp zinc each change.

My drivetrain is quiet, not rattles, no chatter, and the motor runs smooth and clean.

Oil changes cost me about 30.00 every 3k miles, but in these "questionable" engines, i do feel like this makes a difference.

time will tell if this is as reliable as the 18.

Edit: I know that a lot of people on here have posted the generational changes from the early non vvt and non vvl (or combined) engines. But the 3.6 in the current generation is used in other global markets and calls for 5w20 or 5w30 depending on region. The Axles also call for 90w140 from Dana's site and the ZF lifetime transmission fluid according to ZF is for 60k miles.. Which to me at least means it's highly likely CAFE is who is dictating the oil numbers, if not you would think they would be identical globally.
