Beschreibung
Zusammenfassung:	Provided is a lubricating oil composition containing a base oil (A), a phosphorous acid ester (B) having at least one sulfur atom-containing group having 2 to 20 carbon atoms, the sulfur atom-containing group having at least one -(S)x- group (x is an integer of 1 or more) between two adjacent carbon atoms in a structure of an alkyl group, a thiadiazole-based compound (C), and a benzotriazole-based compound (D), wherein a content of the component (C) is 0.01 mass% or more and less than 0.60 mass% based on the total amount of the lubricating oil composition, and a content of the component (D) is 0.02 mass% or more and less than 0.20 mass% based on the total amount of the lubricating oil composition.
