New Mobil 1 C40 GT 0W-40

[userfriendly]

Jeeez so many 0w40’s out now! I just ordered some ESP x3 for $6.26 a quart from an Autozone deal they have going on. Which 0w40 would y’all consider to be the best currently?

Delvac.

I wish Mobil would include a volume knob with each purchase......

One that goes to 11?

For one thing a 0W winter rating would be absolutely irrelevant to racing.

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.
