Mobile1 not fully synthetic anymore(SuperSyn)?!?
This is what I am hearing from various sources:
Castrol Syntec uses a Group III hydrocracked base stock but call it synthetic. The Group III hydrocracked base stock is a super refined crude oil stock, i.e., dino. Mobil 1 lost that advertising battle in court against Castrol, so they starting to mixing some Group III hydrocracked base stock in their "synthetic" oil.

I hadn't heard about such a lawsuit, but Mobil 1 was cracked/super-refined petroleum when it came out in 1975. The PAO came later.
How that chart can claim "most popular" and leave out AMSOIL, Redline, & Royal Purple is beyond me...
