Honest question.
I don't think the air compressor companies even know themselves. For one of the compressors at one of my businesses, they have conflicting, mutually exclusive recommendations across the page from each other in the manual. The one page says to use a non-detergent 30. The next page says to use, specifically, Mobil 1 10w30. Last time I checked, M1 10w30 was not a non-detergent oil. I just use the monograde anyhow, and Castrol sells the ND 30 up here, and at a third of the price that Home Depot or the equivalents sell dedicated "compressor oil." The other alternative would be compressor oil from one of the oil company distributors. Pricing is good, but package size might be a little inconvenient, unless I'm planning on throwing the container in the back of my F-150 and changing the oil in every compressor in western Canada.
