You keep saying that but never back it up.
0W will likely be a thinner basestock, with a lot more VII than a 5W or 10W...that's a downside, instantly and automatically.
e.g a 5W30 is likely to have 30% greater basestock viscosity, and less than half the VII of a 0W30...less polymers to shear, and when they do, more robust basestocks to back it...(0W20 will have slightly higher basestock viscosity and much less VII than the 30 also)
OP, I'd be inclined to 5W30 (or 5W20 synth) if you want more protection...If you want to stay with 0W, and you are using an ILSAC oil rather than one of the European style A3/B4, stay with say Mobil 0W20 rather than one of the Unicorn "Japanese" brews.

If M1 0-40 is a downside compared to a 5-10-40, then why does Porsche recommend M1 0-40 in all their models that I know of? Just asking.
