Title
(EN) LUBRICANT OIL COMPOSITION
(FR) COMPOSITION D'HUILE LUBRIFIANTE
(JA) 潤滑油組成物
Abstract
(EN)
A lubricant oil composition comprising: a lubricant base oil; (A) a calcium salicylate detergent in an amount of 0.005 to 0.03% by mass in terms of calcium content relative to the whole amount of the composition; and (B) a phosphorus acid ester compound represented by general formula (1) in an amount of 0.01 to 0.06% by mass in terms of phosphorus content relative to the whole amount of the composition. (In general formula (1), R1 and R2 independently represent a group having 5 to 20 carbon atoms and represented by general formula (2).) (In general formula (2), R3 represents a linear hydrocarbon group having 2 to 17 carbon atoms; R4 represents a linear hydrocarbon group having 3 to 17 carbon atoms; and X1 represents an oxygen atom or a sulfur atom.)
