FUEL EFFICIENT ENGINE OIL COMPOSITE

摘要

Provided is an engine oil that has excellent corrosion and wear protection capabilities and excellent fuel efficiency. The disclosed fuel efficient engine oil composite contains an organic molybdenum (Mo) compound with at least 0.02 mass% molybdenum and an alicyclic epoxy compound in a lubricant base oil and preferably uses molybdenum dithiocarbamate (MoDTC) as the organic molybdenum compound, a compound that that has ester bonds and two epoxidised cycloalkanes as the alicyclic epoxy compound and a compound that has a dynamic viscosity of 4.5 mm2/s or less at 100 ºC as the lubricant base oil.
