Abstract: The present invention provides a lubricating oil composition excellent in wear-resistant properties and frictional characteristics. The present invention relates to a lubricating oil composition containing a lubricating base oil(A) a complex obtained by reacting a metallic salt of dithiophosphoric acid having lipophilic groups, the average number of the carbon atoms of which is 4 or more, with a primary alkylamine having 8 or less carbon atoms, and(B) at least one kind of compound selected from the group consisting of oxymolybdenum sulfide dithiocarbamate, oxymolybdenum sulfide organophosphorodithioate, fatty esters, and organic amides.
