What oil for a "4"?

I've been out of antique bikes for many years now, but every once in a while an old friend or customer drags me back in.
I have to do a service on a "4" and I can't remember what kind of oil to use.
Being it doesn't touch the clutch, I'm tempted to use a modern synthetic multi-grade.
Thanks in advance.

are you talking about a inline four ? if so i would say that your choice would swiftly kill that engine imho.

Hard to imagine that anything back when this thing was made is as good as a synthetic multi.
I could be wrong.
I think they call for straight 30...maybe 50...
But anything written in my books will be from 75 years ago.
So...what are the guys who actually run these things actually running?
