Royal Purple. Engine Damage In The Long Term?

quicksilver08

Have any of y'all done an oil analysis after 6k to see if the RP is going bad or just judging by its color? I've run rotella in my diesel out to 10k miles and could have gone another 3k had I wantednto according the UOA's. Did the same thing with delo. My car has had regular old cheap castrol in it for the last 39k miles and a regular old wix filter and no issues to date. I recently switched to rp this past oil change but still a wix filter. Ill run this out to 6k and change it then and wont worry about it at all. Although I will switch to Mobil 1 cause its way cheaper and I saw no difference between rp and conventional oil.

Also, all oils designed to be run in diesel engines have very low zinc these days. Including rotella. If they didn't it would clog up and destroy the dpf filter on the truck. There's more to it than that but its 5am and I'm not typing it out on my phone.
