Question about Refrigerators
R 404a compressors use ester oil, this oil can be used with old and new refrigerants.
R502 and R408a compressors used mineral oil, that oil cannot be circulated by new HFC refrigerants like R404a.
So if you know the oil is compatible and the refrigerants have very similar cooling characteristics ...I can't see y not.
