Re: Anybody using Royal Purple in there v6 engines??
I've had tremendous luck with RP in my boat, which also has a 5.7L, though Chevy block.
Haven't switched yet in the JGC, but if you can find proper RP oil spec for your Pentastar, I'd go for it.
Seems cheesy I know, but the RP stuff is noticeably slicker than most syns and dinos I've used.
