Also to know is, what type of PAG oil should I use?
With R-134a, there are primarily three different viscosities of PAG oil being used: PAG 46, which is the most popular viscosity oil; PAG 100, which is also common; and PAG 150, which is not often used, but it is still required for a certain compressor used in some GM vehicles from the '90s to the early 2000s.
One may also ask, when retrofitting an A C system from r12 to r134a what oil should be recommended? R-134a systems require PAG (polyalkylene glycol) oil of a certain grade. PAG oil is hygroscopic, meaning that it readily absorbs moisture from the air. Never leave the cap loose when storing PAG refrigerant oil. Some manufacturers recommend using less hygroscopic POE (Polyol Ester) oil instead of PAG after a retrofit.
Keeping this in consideration, what type of oil do you use with r22?
What kind of oil does a AC compressor use?
The two categories of oils commonly used in the compressors are mineral or synthetic oils. One type of mineral oil (MO) called Naphthenic is commonly used. Synthetic oils such as glycols, esters and alkylbenzenes (AB) have been used in the refrigeration applications for some time without any problem.
