In my '52, for 5 years I have run straight weight SAE 50 engine oil, based on the recommendation of Charles Talbert at M-series rebuilds over on the PWA site.
No issues whatsoever.
It is said that 50 engine oil is the same "weight" as 90 gear oil, but does not have the sulfur of gear oil that can cause issues in any gearbox with bronze parts?
Maybe it is overkill for a non-synchro but it works.
