I know there has been lots of post on this type of compressor but not his model.I have been give a compressor that I can not find info about. It is a Stewart Warner/ Southwind corp 15 CFM 3500psi 4 stage compressor looks alot like the 4 cfm models at protech. Protech has no info so I was hoping someone here may. from reading previous post I think that Mobil Jet II is the oil I need don't know how much. I have a 5HP honda motor but don't know if it will be enough. Don't know what RPM. I will only be using it for air, no mixes. Any help would be appreciated
