However Im puzxled by this, Im not aware of that viscosity mutigrade existing back then, pretty much it was just 20w50, though Im not saying it wasnt around...
Dont go crazy with zddp, you need 800-1200ppm for wear resistance, any more can actually accelerate wear just like too little.

Thanks Andy, much appreciate your reply too.
I'm keen to use an engine with ZDDP already in it (unlike the modern oils for cat/converter engine).
I've tried to attach the appropriate page from the manual here.
My big concern is to not encourage wear.
I'm also puzzled why Amazons are not listed when I search 20w50 oils manufacturers - and - why Castrol GTX SAE 10w30 is seemingly so darn hard to find here in the U.K. (Online anyway)
Anyone know of a solid stockist for Castrol GTX SAE 10/30, in the U.K.?
Cheers
