Most of us know to get our 392s in when your "change oil" light comes on. But did you also know that your oil change interval includes an "or, every 6 months" rule also? Please review your year's owner's manual (the supplement for the 392) but my 2022 reads:
The oil change indicator message will not
monitor the time since the last oil change.
Change your vehicle's oil if it has been six
months since your last oil change, even if the oil
change indicator message is NOT illuminated.
On another Jeep forum, a 392 owner posted that his engine blew and was not covered under warranty, for this reason. The vehicle never actually hit 6,000 miles and went far past 6 months without an oil change. I don't want to delve into the "what-ifs", warranty claim BS etc. etc of this circumstance as it's not my Jeep. The point here is just to inform folks if they are unaware. While I routinely check my fluids, I rely on the dummy light to tell me when an oil change is required, and not on a calendar. A mistake which I will now correct especially given I don't put many miles on my beastie. My service advisor at the dealer has never mentioned this surprisingly enough, even when my Jeep was there for other reasons. At the end of the day though, it's my responsibility.
(In case anyone goes to the Mopar site to pull their service manual, for the 392 supplement, you have to go to "Other". And pull up the "Rubicon" supplement. This is the 392 supplement even though it is not listed as such.)

And I take it to this dealer because they're much better than the two I used to use for my JK. Jeep really makes it difficult to like Jeep.
