Refrigerant Oils

NOTE: Use ONLY the specified oil for the A/C system or compressor. Always check the underhood A/C specification label or A/C compressor label before adding refrigerant oil to A/C compressor/system.

Use only new, moisture-free refrigerant oil in A/C systems. Refrigerant oil is highly refined with a very low moisture content. Oil container must be tightly closed when not in use, or moisture from air will be absorbed into refrigerant oil.

Refrigerant R-134a systems use Polyalkylene Glycol (PAG) refrigerant oil. Using a mineral oil based lubricant with R-134a systems will result in A/C compressor failure due to lack of proper lubrication.

Different compressors have different lubrication requirements and use different specified Polyalkylene Glycol (PAG) refrigerant oils. Use only specified PAG refrigerant oil for the appropriate system and A/C compressor. Always check the underhood A/C specification label or A/C compressor label before adding refrigerant oil to A/C compressor/system. See the REFRIGERANT OIL APPLICATION table for specific refrigerant oil applications.

NOTE: PAG oil absorbs moisture very rapidly, 2.3-5.6 percent by weight as compared to a mineral oil absorption rate of .005 percent by weight.
