I bought a big reciprocating air compressor. 100 CFM. It was shipped without oil. What oil should be used in such a thing? I have looked at McMaster-Carr, they have ISO grade 68 and 100----synthetic, they have 32, 68, and 100. The synthetic is about 4 times higher. Rotella 15-40 probably doesn't work, right?
