Embraco EGU70HLC for use as an airbrush compressor

Hello again!

I have a Embraco EGU70HLC compressor I would like to use as a compressor for my airbrush. My question is that kind of oil should I use, and how much? I have heard I should use machinist oil and that I should never use motor oil ( the kind intended to cars becausese it contains petroleum Distilates) So do any Experts out there have Good advise? Can I use Air tool oil? Mineral oil? PLEASE help:(

Any advise would be greatly appreciated.

Thanks
Shane
