PSA1 Porter Cable compressor oil

[bigsteve]

My Pro Air 5 hp 20 gal air compressor said to use PSA1 PC compressor oil. Is there any other oil that I can use? And is this PSA1 oil a 30w non detergent oil?

I think this is one of those occasions that those SA rated oils are ok for what you need.

At one time PC also liked the use of Mobil 1 15w50, which is what I use in my PC compressor. It's worked just fine for the last 7 years.
