Don’t think he was saying they don’t use assembly lube. Sure they use some kind of oil. But is it actually stout enough, in such a small amount, to make a meaningful contribution to the motor oil’s additive pack? To the point where the upsides of leaving it in place outweigh the negatives? Not convinced.
My opinions and educated assumptions only:
1) Mopar is not likely to use a super expensive assembly lube that’s chocked full of ZDDP or moly. It’s a modern, robot assembled engine with a roller cam and tight tolerances.
2) Even if they do use a magic lube, it is not typically best practice to leave that crap in there past 500 miles.
3) The EPA sucks. They have managed to simultaneously reduce the protection of motor oil while also bullying companies to extend the OCIs. This was a recipe for disaster from the start.
