Probably been asked before, but here goes….

10w40 or 20w50?

Obviously mineral for the old air cooled donkey….


Book says 10w40

10 -40.., 20-50 is too thick for cold starting really and although it's air cooled it does get hot enough to breakdown 50 weight.

Silkolene 10/40. Hopefully still made in the UK.

Thanks for that.

My next oil change will finish off my Motul and I was wondering what others were using, I’d found someone selling the Rock Oil stuff but it was only the 20w50.
