Refrigerant Oil

Refrigerant oil type Polyalkylene Gycol (PAG)

NOTE:
Oil Used in R-134a-Charged Systems

A synthetic oil is used, which is totally different than the mineral based oils used in Freon-R12 Systems.

R-134a Systems require Polyalkylene Glycol lubricants, often referred to as "PAG" oil. Use of R-12 compressor oil in R134a Systems will cause the compressor to seize and fail. The R-12 mineral oil does not stay in solution in R-134a. In addition, R-134a compressor should not be used in an R-12 System. Long term damage and corrosion will result.

The GREEN R-134a system labels, usually located near the top side of the fan shroud in the engine compartment, will display the refrigerant requirement for R-134a Systems.

R-12 Systems will have a BLACK label in a similar location.
