Like the Pennzoil Ultra Platinum 0w40 (same as Mopar 0w40), it has a lot of moly. Not bad.
Also, from the safety data sheet on it, Schaeffers 0w40 is mostly PAO base oil, good too.
Calcium looks low enough to avoid LSPI in DI or DI-turbo engines.
ZDDP concentration is comparable to most MB 229.5 0w40 euro oils.
I'd recommend this (or PUP 0w40 too) for old muscle cars, Corvettes, Camaros, Mustangs, trucks that tow;, and would be great for turbo Subaru's as well.
Of course SRT Chrysler engines too!
PUP-Mopar 0w40 is not PAO like this one, yet Shell may have access to better anti-ox chemicals etc. to easily compensate, and they do use Group3+ anyway.
Formulators can choose PAO as a solid foundation, yet its not necessary if you have an army of PhD's and volume of patents in big lab buildings (Infineum, etc.) creating weird additives to compensate for using just Group3+.
Anybody suffering from fuel dilution where their engine called for a 0w20 or 5w30 etc. originally, can benefit from the extra visc.
