More Information
Summary:Disclosed is a lubricant composition obtained by blending an amine antioxidant (A-1) and a compound (A-2) containing phosphorus and/or sulfur into a base oil which is composed of a mineral oil and/or a synthetic oil. The amine antioxidant (A-1) is blended into the base oil in such an amount that the total nitrogen amount is not less than 800 ppm. This lubricant composition enables to obtain a compressor oil which is excellent in all of thermal/oxidation stability, sludge resistance, lubricity, long life and water separation property.
