In a recent thread on one of the f-body message boards I frequent, the topic of Royal Purple came up and I mentioned my problems with it thinning out on me. You'll never believe the funny response I got from one guy who spoke to someone at RP about this. What do you guys think of this quote:
quote:So according to him my oil is adjusting itself for the right viscosity needed? I can't see how that's even possible. [ September 15, 2003, 01:32 PM: Message edited by: Patman ]
I also spoke with [email protected] and asked about the thinning you are suggesting. The difference with RP is that it finds the proper viscosity for your engine and changes its viscosity for the best protection. If it is thinning out then the tolerances needed to protect you engine in the best possible manner are requiring the oil to become thinner to get within those tolerances for best protection. RP then stays at such level to aid in protection for startup and not be much thicker as to not give initial protection.
