Did you not see the massive amount of Blackstone data I posted in post #76? I'm aware of how this works and why I asked the question. Can you tell which oil worked better or worse in that mountain of data? It's a variety of different oils as I stated.
My question still stands - what specifically in your BS reports indicates that T6 did any better than any other oil would have in your car/mower/etc.? BTW, I don't think T6 is a bad oil, it's just nothing special and there are better choices in a 40 grade for the same/similar price based on the approvals those oils carry and what they mean w/r to how these oil perform in your gasoline engine. I can run about any oil in my car and the BS reports will look the same/similar w/r to wear metal rates.
