Every test gives a little glimpse at the quality of the product overall.
Given that the big brand oils (PP, M1, Castrol edge) have similar NOACK, (10-11%) you can read into their base oil quality from the cold pour results. Higher quality base stock has a higher natural VI = better cold performance.
This is why I was surprised M1 wasn't able to match PP since it is supposed to have some PAO base which has a higher VI than GrpIII.
Maybe M1 removed most of the PAO content from their 5w30 formula since GrpIII oils keeps getting better. SOPUS GTL appears to be the best GrpIII, so their PurePlus marketing has some truth to it.
