Joe,
thanks for the corporate take.
go grab oil measure viscosity in your viscometer.
heat it 100 F put it back in your viscometer
wonder why you are so wrong?
the oil "acts like" SAE 0w when cold it isn't actually thinner when cold it's resistance to flow is actually greater. just not as great as it would be if it were a "straight weight" oil.
multi viscosity oil is full of friction modifiers, to make it more stable over a wider temp range, but the oil doesn't act inversely from normal oil in regards to temp vs viscosity, it is just less of a swing
and how can you tout your (snake) break-in oil and then say the best thing to do is follow manufacturers recommendation?
don't forget increase in oil weight also contributes to an increase in at the bearing temperature because of lower flow and higher pressure, increased strain on the oil pump drive....
I see you are trying to be helpful but it is hard with a banner that big and a corporate axe to grind,
