New Mobil 1 C40 GT 0W-40

Semi pro ice racing on Minnesota lakes when it is -28.
How is that relevant? 0W is cold pumping measured at -35. That does not mean 5W cannot operate at lower temperatures.
Then, no racing engine is started just before race. They will start before that, probably in garages. After that, it is irrelevant whether it is -28 or -50 outside or whether oil is 0W or 15W.

It’s called not understanding the question.
