    摘要: Disclosed is a novel diesel engine oil composition for fuel efficiency and endurance performance. The diesel engine oil composition may maximize frictional resistance and wear resistance by facilitating the formation of a lubricating film on a metal surface, extend an oil change cycle with excellent engine protection ability, and improve fuel efficiency due to friction reduction. The diesel engine oil composition include: base oil; a calcium-based or magnesium-based sulfonate detergent dispersant; a viscosity index improver selected from the group consisting of a diene copolymer, a polystyrene-diene copolymer and a hydrogenated polystyrene-diene copolymer; and a low friction agent including molybdenum dithiocarbamate (MoDTC) and glycerol monooleate (GMO).
