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?
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.
