    Abstract: PROBLEM TO BE SOLVED: To obtain a lubricating oil composition that has a high coefficient of static friction of a wet clutch, excellent friction properties of a power transmission mechanism and excellent low fuel consumption and is suitable both as a lubricating oil for power transmission and an engine lubricating oil.
    SOLUTION: The lubricating oil composition is obtained by combining a lubricant base oil with (A) an organomolybdenum compound, (B) a zinc dialkyldithiophosphate, (C) at least one kind selected from calcium sulfonate, calcium phenate and magnesium sulfonate having ≥230 mg KOH/g base number and (D) a boron-containing ashless dispersant or a combination of a boron-containing ashless dispersant and a boron-free ashless dispersant in fixed ratios, respectively and has the mass ratio (P/Mo) of P content to Mo content of ≥1.5, the mass ratio (CaMg/Mo) of the total content of Ca and Mg to Mo content derived from the component (C) of ≥3 and the mass ratio B/N derived from the component (D) of ≥0.5.
