forgive me if this has been covered, but i couldn't find anything with the search function. i'm trying to wrap my head around the numbers so i may have this incorrect. looking at the viscocities, it appears that the PP is thinner at just about every temperature except temps below -30C or -35C it also appears that the pour point of M1 is slightly lower at -50 vs -48 for the PP. i've already got the PP 5w30 in the sump, but looking at it more it looks like there is likely nothing to be gained with the 0w30 for my climate. we get down to -20's (F), but i've never seen -30 F (saw -29F once). i chose the PP for cold flowability and notably low NOACK, where the M1 was not published but assumed to be higher with the 0w vs the 5w. am i on the right track with the numbers and some of my assumptions?
