Abstract: An additive for lubricating oil may include a phosphite ester compound (A) having a specific structure and a phosphite ester compound (B) having a specific structure, wherein the (A):(B) mass ratio of the phosphite ester compound (A) to the phosphite ester compound (B) is in a range of from 99:1 to 80:20. Such an additive may be provided to a lubricating oil, capable of imparting wear resistance and demulsibility with respect to a base oil for lubricating oil, and to impart durability even in the presence of water.

Abstract: A lubricant additive includes a monoester carboxylic acid salt (A) represented by formula (1). In formula (1), R1 represents a single bond between carbon atoms of carbonyl groups, or a divalent hydrocarbon group having 1 to 4 carbon atoms, and R2 represents a hydrocarbon group having 1 to 22 carbon atoms. AO represents an oxyalkylene group of one type selected from oxyalkylene groups having 2 to 4 carbon atoms, or a mixed oxyalkylene group of two or more types selected from oxyalkylene groups having 2 to 4 carbon atoms, and n is an average number of added moles of the oxyalkylene group represented by AO and is 0 to 5. M represents organic ammonium.
