Royal Purple is not listed in the Wikipedia, most of the other synthetics are listed. But with Royal Purple being "extremely used, and popular", is not! "I would expect it to be there"!
So I'm toping off oil today, RP, family car. I've used RP for the last 21,000 miles. I'm getting ready to change oil, approaching 6,500 miles. "Curiosity gets me", I pick up my drop light, and look inside the oil port. Disappointed in what I'm seeing! "Oil build up", not a lot, or extreme. I expected better looking than what I saw. "Just enough build up, that I will no longer use RP"!
I'm checking out Amsoil and Redline, I have more reading to do.
