Abstract
A lubricating oil additive contains a partially etherified polyhydric alcohol which has at least two hydroxyl groups and at least one hydrocarbon group having a least one double bond bonded thereto through an ether linkage as an active component. The lubricating additive is added to a lube base oil to form a lubricating oil which imparts excellent wear resistance, scarcely corrodes metallic substances, scarcely swells rubbers or resins and scarcely forms sludge due to thermal oxidation. The lubricating oil is mixed with a refrigerant to give a working fluid suitable for refrigerant compressors of domestic refrigerators, automotive room air conditioners, refrigerators for industrial use and air conditioners.
