Beschreibung
Zusammenfassung:	PURPOSE:To provide the subject lubricant composition containing a base oil or a base agent and a specified dialkylphosphorodithionic acid oxymolibdenum sulfide, excellent in prevention of oxidation abrasion-preventing effect, reduction of frictional and thermal resistances/and low in metal-corrosive properties. CONSTITUTION:An objective lubricant composition containing a base oil such as natural oil or a synthetic lubricant or a base agent and a dialkylphosphorodithionic acid oxymolibdenum sulfide of the formula (R is 4-30C secondary alkyl; X is O or S) and suitable, e.g. for a lubricant for a crank case of a spark ignition- or compression ignition-type internal combustion engine including engines for automobiles or trucks, two-cycle engines, piston engines for aircraft, etc.
