I was looking at M1's product guide pdf at M1 EP in all the various viscosities. The 0W20 has 650 phospherous and 750 zinc, whereas all other viscosities have 800 phospherous and 900 zinc. BUT,the 0W20 EP HM has the 800/900. I'm just curious as to why this is?

I noticed that too in the M1's product guide. They did it in their 0W-20s for some reason. The AFE 0W-20 is the same way, 650 and 750 phos and zinc. The other Mobil 1 varieties and viscosities like the 5W-20, 5W-30, 10W-30 are all 800/900 phos and zinc.

Could it be that EM lowers the Phosphorus and Zinc slightly in the 0w20's because they have a better base oil?

It's my understanding that all HM oils have boosted additives compared to the vanilla flavors.
