However, my understanding is that 0W oil is not going to increase consumption and blow-by during warming up time because obviously that's when it's even thicker than it is at its operating temperature.
I did some reading and found a point that 5w is less reliant than 0w on viscosity index improver to achieve any given operating viscosity rating, and thus is more resistant to shear damage, the culprit of permanent loss of viscosity, which is why it gives more protection in the long term.

If you can share something on the link from one of your resources that would be great especially a reputable source. The poster put the redline video on here for example. I don't mind being wrong as long as we get the right information. I would love to see that. My understanding is that 0W is thinner at cold temps than 5W?
Thanks again
