摘要:
A problem is to provide a lubricating oil composition having an excellent rust inhibiting capability even containing a base oil containing a polar substance that has a function significantly deteriorating the rust inhibiting capability, and a use method and a production method of the lubricating oil composition. The problem is solved by a lubricating oil composition containing a base oil (A) and a rust inhibitor (B), in which the base oil (A) has a gas chromatogram measured by gas chromatography satisfying the particular condition (α), and the rust inhibitor (B) is one or more kind selected from the group consisting of a first rust inhibitor (B1), a second rust inhibitor (B2), a third rust inhibitor (B3), and a fourth rust inhibitor (B4), and satisfies the particular condition (β).
