Default Re: Which pag to use?

Here's one site listing compressor manufacturer and recommended pag oil viscosity; https://crxsi.com/info/air-condition...TION-CHART.htm

Here's another site; http://www.compressor-intl.com/HTML/Sat06.htm

Saturn (and maybe GM) does an excellent job of conveniently leaving out pertinent information like pag oil viscosity by only listing a GM part number....... The only thing they allude to in service manuals is using pag oil for r134a systems.
