Well ok. I've listened to engineers and oil formulators over the years and being an old knuckle dragging diesel mechanic, I'll stick to my beliefs. It reminds me of the argument of what is the most important properties of antifreeze. Does it protect metal from corrosion, boil over or from freezing?
Funny thing is a room full of engineers will rarely agree on a subject. It all falls on what they were taught, read, experienced, etc.
I am not even attempting to sway your belief one way or the other but what I said is a 100% irrefutable fact of the physics of thermal dynamics and the science of tribology and anyone differing from it is simply incorrect. Its not a subject for debate.
