At Checker I see they sell SAE 30 SAE 40 oil. Why couldn't one use a SAE oil in summer?
M1 15w50 says it pumps at -39f and its pour point is -45. 5w30 pour point is -39.
Why wouldn't I use it in winter???

I wounder if I went to a M1 15w50 I would still suck oil at high rpms like M1 0w40 and M1 10w30 does?
