Abstract (en)

[origin: EP1878784A1] A long-life fuel-saving engine oil composition which comprises a mineral and/or synthetic base oil; an amine antioxidant and a phenolic antioxidant added to the oil in a total amount of 1.2 mass % or larger in which the ratio of the mass amount of nitrogen (N) contained in the amine antioxidant to the mass amount of oxygen (O) contained in the phenolic antioxidant, (N/O), is 0.20-0.50; and MoDTC incorporated in an amount of 0.055 mass % or larger as molybdenum element amount. There is provided the long-life fuel-saving engine oil composition which has excellent oxidative stability at high temperatures and retains low-frictional properties over long.
