A/C Compressor PAG Oil Application Chart

Copyright AA1Car

Automotive air conditioning compressors require specific types of lubricants. Most 1996 and newer A/C systems use R134a refrigerant and require some type of PAG (polyalkylene glycol) oil for the compressor. If the wrong type of compressor oil or the wrong viscosity compressor oil is used, it may damage the compressor. In fact, the main reason for a newly installed A/C compressor to fail is using the wrong type of compressor 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. POE (polyol ester) oil is usually specified for hybrid cars that have electrically-driven A/C compressors because it is non-conductive. Using the wrong oil may allow current to short circuit back through the A/C compressor, creating a shock hazard.

Mineral oil should only be used in older R-12 A/C compressors because R-12 will not mix with R-134 refrigerant.

"Universal" A/C compressor oils are 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 oil specified by the vehicle manufacturer. General Motors recommends GM lubricants only (PAG-PSD1 #19260643 for 2013/14 Cadillac XTS, and PAG-ND12 #19299051 for 2013 Cadillac ATS). Universal compressor oils should NOT be used in R-1234yf applications.

The following is a list of recommended lubricants by compressor manufacturer. you can identify the compressor mfr. by looking for an ID tag or label on the unit (or see the reference illustrations at the right and left):

A/C Compressor Oil Capacities

If you are replacing a compressor or other A/C system component, it is important to replace any compressor oil that has been lost when parts are changed. The total system oil capacity for many late model passenger car A/C systems is only about 4 ounces (120 ml). A low oil level can starve the compressor for oil and lead to compressor failure.

CAUTION: Do NOT overfill the the A/C system with too much compressor oil. Too much oil can hurt cooling performance.

Use the following guidelines for replacing compressor oil when changing A/C components:

Compressor.........1.4 oz
Condenser..........1.0 oz
Evaporator.........1.5 oz
Accumulator........1.0 oz
Hoses..............1.0 oz

The total amount of oil added to compensate for parts that have been replaced should NOT exceed the total oil capacity of the system. If you don't know what the total oil capacity is, check the underhood A/C service decal or look up the information in the OEM service literature.
