Worth bearing in mind that when these engines were designed there was no such thing as 20W/50 oil, or any other multi grade.
My old BSAs from twenty years later were designed to run on straight 30 grade in the winter, 40 grade in summer, like most other engines. Mind you, I blew both of them up because Duckhams 20W/50 wasn’t all it was cracked up to be. .
More like running out oil than running in oil.

Built like a gun... could go BANG!
