It's all fine and well to talk about requiring time and heat to activate additives, or AW layers being reduced or not replaced at a good rate, but unless we can quantify that, we have a bit of a problem.

There was no need to take the residual contaminates into account. They weren't measuring wear in the engine. The cobalt 56 in the lifter used in the bench apparatus was the proxy for wear. Traditional engine wear metals as we know them in UOA were not in the equation at all. The engines were merely a source of used oil.

Okay, I get you know. Not having read all the papers in question here makes things a little murky.

Agreed. I change on the Hank Hill schedule.
