Alkylbenzene (AB) oil is miscible in HCFC refrigerant.

Explanation:
In refrigeration lubrication, the ability of the oil to mix with the refrigerant (miscibility) is key for keeping the compressor properly lubricated and ensuring the oil returns to the compressor with the refrigerant flow. Alkylbenzene oil is formulated to be compatible with HCFC refrigerants, so it dissolves well in those refrigerants and forms a single phase rather than separating into an oil layer. This makes AB oil a common choice for systems using HCFCs such as R-22, helping maintain lubrication where the refrigerant is present.
