What motor oil for '47 Deere model A? Non-detergent?

Interesting discussion on non-detergent oil. I have a old air compressor it pumps good still today and meets my needs of today which is mainly airing up tires. Years ago when I purchased the unit it had a tag attached that said "Warning" use only non-detergent oil. I have often wondered if the compressor has Babbitt Bearings.

Over the years a quart of non-detergent has increased and increased. Ingersoll Rand really loves there's.

Long ago, about 1962, I bought a used 1950 Oldsmobile. $100, clean, a nice car. One of GM's first 'modern' V8s. At 100k miles the hydraulic lifters were apparently crudded up and there was a lot of valve clatter. I tried Delo high-detergent Diesel oil hoping to clean the engine. Nope. Even with several oil/filter changes this apparently got even more debris circulating and into the lifters and they clattered worse. Don't Do This.
