Ro3bert Posted March 18, 2018 Share Posted March 18, 2018 I have an old Super Quiet 20 compressor that has to have oil for the compressor. I have no idea what sort of oil to get for it. It doesn't need oil now but it certainly will in the future. What sort of compressor oil should I be looking at? I've been contemplating power steering oil as I believe it is hydraulic oil but I could be wrong. Whatever brand of oil the unit originally called for and where to get it has been lost in the mists of time. Robert Quote Link to comment Share on other sites More sharing options...

Ro3bert Posted March 18, 2018 Author Share Posted March 18, 2018 Thanks Andy. I checked the site and was surprised to see they are still in business. Contacted them about the oil question and am waiting for their response. Quote Link to comment Share on other sites More sharing options...
Ro3bert Posted March 20, 2018 Author Share Posted March 20, 2018 Got a reply yesterday. The oil costs US$24.50 for 24 oz. It's a special oil, other kinds can ruin the O rings and get into the pressurized air (at least that is what the owners manual says). Thank God I don't need any now. The manual calls for one year intervals for oil change but I have never used it enough to warrant an oil change. Interestingly the compressor has a date of manufacturing as 1986 and that is when I bought it. Quote Link to comment Share on other sites More sharing options...
