Ok, the title is sensationalized, but I performed my first oil change today at 1000 miles with oil other than Penzoil. In my JK with the 3.6, I had the notorious lifter tick. It went away with Castrol and overall, the engine sounded and felt smoother. The 392 is a noisy beast with ticks, whistles, and tapping so I figured between oil changes, I’d try the Castrol 0W40. No difference. Someone said that Castrol changed their manufacturing process in 2018 so maybe that‘s it, or maybe this engine just likes to make a racket. Anyhow, I’ll probably just use the Penzoil in the future.
Some takeaways:
1. The drain plug is SAE with the steel pan, 1/2 inch. 13 mm was too loose.
2. After removing the filter, oil gets inside the dust cover of the steering stabilizer and keeps dripping. I’d try to cover that with something beforehand.
3. Took the full 7.5 quarts
4. Oil pressures at idle is 30, cruising at 51-53, and wot 61-65.
5. Drain plug was torqued correctly from the factory, we’ll see how the dealer does for the free oil change.
As far as brand of oil, I suspect any of the premium oils will do fine. It probably has more to do with loyalty and experience than actual differences. My experience was what led me to try the Castrol, but now that I have, nothing changed so my loyalty is reset. I don’t think these engines will fail because of the brand of oil you used as long as you take care of it in the first place.
I’d be interested in anyone else’s experience with the other brands.
