I was browsing the M1 site looking to see what was GF6 and SP when I noticed a couple of interesting changes to a couple of their oils.
AFE 0w30 always had a lower cSt than vanilla M1 5w30 at 10.9 v. 11 however today AFE meets the new standards and the cSt had been raised to 11.5.
Truck and SUV decreased their cSt from 11.5 to 11.1 which is what vanilla was almost at.
Both of these oils are GF6 and SP.
The M1 product line is awfully confusing because of overlap and changes and now Pennzoil is on that bandwagon too.
