Compressor Oil
The compressor oil dissolves in the refrigerant, circulates through the air-conditioning cycle, and functions to
lubricate the compressor. But the conventional compressor oil for R12 doesn't dissolve in R134a, so it doesn't
circulate through the cycle, and the lifespan of the compressor is considerably shortened.
It is still essential to ensure that the correct refrigerant oil is used. R12 systems were lubricated with mineral oil,
which is totally unsuitable for R134a systems. The letter require PAG oil, which mixes very well with the refrigerant
and provides ideal lubrication throughout the system.
*PAG: Polyalkylene glycol (Synthetic oil)
