Royal purple - oil analysis results

I would highly suggest switching to a better oil like Mobil 1, Castrol Syntec, Pennzoil Platinum, Red Line, AMSOIL or basically anything else. It honestly doesn't look like Royal Purple is doing too well for your case. I've seen much better UOA's at that mileage from pretty much every other synthetic out there.

Hopefully some people start to wise up about this over-priced, mis-marketed product. Ugh.

Oh, and the magnesium is a "Detergent/dispersant additive"
