Can anyone offer any justification for these magic elixirs that include zddp or zinc over my long time preferred Mobil 1 at 25 bucks a Six Pack on sale at Costco, when running a roller cam.
Nope, nor can they really justify it for most slider cams either.
They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.
