If your vehicle was originally charged with R12 refrigerant, for example, the oil type specified, ‘mineral’, will not apply. Additionally, General Motors issues Bulletin # 02-01-39-004B replacing PAG 150 oil with a lower viscocity oil. Thus, TechChoice now indicates PAG 46 (P46D) oil for those vehicles. All Engines w/ Front & Rear AC …
When to add PAG oil to the accumulator?
The accumulator stores pag oil when the system is off just like all the other components, when one flushes or replaces all or individual parts oil must be replaced. You add a specific amount of oil to each component e.g. compressor, accumulator and so on.
What can be used as a substitute for PAG oil?
PAO (Polyalphaolefin) oil can sometimes be used as a substitute for certain PAG oils if the compressor manufacturer approves it. CAUTION: PAG oils should NEVER be used in hybrid vehicles because it is electrically conductive.
Do you have to use PAG oil for an A / C compressor?
“Universal” A/C compressor oilsare often PAO-based and are not the same viscosity as the PAG oil recommended for a specific type of compressor. This can lead to poor lubrication and premature compressor failure. Newer vehicles with R-1234yf A/C systems require a special 1234yf compressor oilspecified by the vehicle manufacturer.
