Re: RP vs valveline
Wear metals (Iron, Copper, Lead, Alum, Chromium) look great Nate - a great example/comparison showing how overpriced Royal Purple is. Even though it has some Molybdenum in it, RP doesn't use as much as Delo 400 and less than 1/2 that Schaeffer's uses and charges alot more for their product.
