Have you any idea what engine oil was used when you worked on the engines.
I know its a lot to ask where it was a long time ago
Thanks so much

Yes Mike, It was a light SAE 20 diesel engine oil because it made it easier to start as most of them were hand cranked.
I still had some of the Petter equivalents till fairly recently and I had no problem using a modern 15/40.
Hope this helps.
