Older API SP spec. Castrol is the most erratic in implementing API SQ. If you have a turbo or a car with a timing chain, you want API SQ.

TBD on if it'll help with head gaskets, but I'm early filling it on my Pentastars just as a maybe.

With my half price GCs from Citi, this would have been an amazing deal if it was actually available anywhere. :x

Timing chains have been around a lot longer than SQ. Sorry, this is just pointless fearmongering.

SQ has been out a whole 1 year now. I would be more concerned about it being 5w-20 than SP or SQ.
Still have a stash of SL and SM oil I have to go through before I even begin to start using my SN/SN+ stash. Not sure if I have any SP oil in my 30 gallon stash.
Newest vehicle I have is a 2018, and it don't care. None of mine are turbo, and none are models with timing chain issues (well, my '02 F150 with a 5.4 2V has some know issues, but when I replaced the engine with one from a junkyard I had new chains and guides put in).

But does not matter, none around me in 5w-20 or 5w-30.
