Hello,
I'm reading conflicting info on oil type/ grades.for my 1939 350 model C
So....
Which oil for the engine
Which oil for the gearbox
Which oil for the primary chain case

I'm sure many of you will know the answer but all I can find is grades for more modern machines.

Thanks in advance

20/50 mineral for the lot will do.
