Re: Anyone have problem with their posi chattering?
Last time I opened a new bottle of Royal Purple, it smelled burnt. I don't care what anyone says about it being "more refined", NEW oil, synthetic, or dead dino, should NEVER smell burnt.
I use Castrol Tectron 75W-90. It contains the friction modifier already, and smells like new oil should. I have used it in several different trucks, with a range of different axles, used for different purposes. I have never had a problem.
