    IS it one of the very early total loss oil systems (plunger and sight glass for the dripper) if its been apart and cleaned they will run ok on any oil as so lightly stressed, I have been about a long time and use a high detergent oil in 100 plus year old early cars, the only thing with early type of cam followers they need help and only the high detergent oils still had the additive that supposedly works.

    The original oil would have been SAE 30, a commonly used non-detergent oil that you can still get from most good car accessory shops.
