▎ 摘　　要

NOVELTY - Low friction diesel engine oil comprises 70-85 wt.% base oil, 2-15 wt.% viscosity index agent, 0.1-2 wt.% friction modifier, 3-18 wt.% complexing agent, and 0.1-1 wt.% pour point depressant, where the friction modifier comprises 70-78 wt.% organic molybdenum, 20-25 wt.% organic ester and 0.01-10 wt.% nano particle. USE - Low friction diesel engine oil. ADVANTAGE - In the low-friction diesel engine oil, friction modifier is obtained by organic molybdenum, organic ester and nano-particle compound, friction film can be formed on the friction pair surface, improving the friction wear performance of the diesel engine oil, and reducing the coefficient of friction engine oil. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing low friction diesel engine oil comprising mixing the base oil, viscosity index agent, complexing agent and pour point depressant, preparing mixed material, and mixing the friction modifier with the mixed material.
