The formulation may have changed though if PPPP has decided to transition to Mg in dexos1 Gen 2/API SN Plus.
Point taken though if She’ll has not reformulated, (and we have uoa’s that they did) then they are way behind the eight ball.
Of course, Shell does reformulate them when they announce that they have done so.
There was the major "PurePlus" reformulation in 2014 when they switched from Group III to GTL.
Late in 2017 they reformulated to dexos1 Gen 2 -- aka high-magnesium, high-moly.
Next month API SN Plus is coming but I think it will be only a label change, as it merely includes the LSPI test such as in dexos1 Gen2.
However, unlike some who criticized the 2014 PDS data being too old, there were no formulation changes between 2014 (PurePlus introduction) and 2017 (dexos1 Gen 2 introduction).
I like the high moly in dexos1 Gen 2 oils. In Pennzoil's case it's probably trinuclear moly since Infineum is owned by ExxonMobil and Shell. Too bad that HDEOs tend to be lower in moly and you lose some of the wear-protection benefits you gain from thicker base oils such as 15W-xx.
It's also interesting that boron has come back. I also noticed a dash of titanium.
