[QUOTE="UnleashedBeast, post: 10231770, member: 112023"] Race oils have high amounts of ZDDP, very true, and for good reason (high temps, high pressures, high stress). The con of race oils, low TBN content (detergent additives). Your Red Line 5W-50 should have ample amounts of ZDDP in normal form, as it's an API SL style formulation. If you need more than what is formulated, why not choose an oil that has ALL the requirements for your engine. Do I know more than the manufacturers, never (they make political decisions, most are not always what is best for the end user). Do I know more than just about everyone else who posts here....more than likely. Oh, and I care because....AMSOIL formulates high ZDDP additive packs in their 10W-40 and 20W-50 street oils. I don't have to add anything extra to get the protection my engine deserves. [/QUOTE]
