Hi so its that question again, so multigrade or an SAE 30 , I am looking at using Morris SAE 30 Golden Film, any thoughts

Any is better than none is my mantra, if it is still inside it's even better.

Straight 30 was the oil specified before multi grade 20/50 appeared on the market in the late 1950's, either is fine but I use 20/50 by choice.

15w-40 as it works and can be had at any fuel stop and Tesco has it on offer a lot
