That's the whole point of having it analyzed. You run it for a while and send in a sample. You don't have to take anyone's word here, or what an oil company says. Blackstone will tell you exactly what that oil is doing in your engine so you can make the necessary adjustments. Just because your concoction has all the sn ratings doesn't mean it's doing a wonderful job in your particular engine.
That's why I say, unless everyone is sending in samples to show how well some oil is doing in an engine this whole discussion is honestly meaningless.
