Abstract (en)

The present invention provides a lubricating composition for internal combustion engines comprising a lubricating base oil in an amount of about 100 parts by weight, and (B) a molybdenum dicarbamate in a amount within the range of from about 0.1 to about 3.0 parts by weight, said lubricating base oil consisting substantially of a hydro- cracked lubricating base oil in an amount of more than 70 % by weight (on the basis of the amount of the lubricating base oil) wherein the hydro-cracked lubricating base oil is manufactured by hydro-cracking petroleum fraction and has a kinematic viscosity in the range of from about 2 to about 10 cSt at 100 DEG C., said hydro-cracked lubricating base oil containing aromatic hydrocarbons in an amount within the range of from about 3 to about 15 % by weight, sulfur in an amount of less than 50 ppm by weight, and nitrogen in an amount of less than 5 ppm by reight on the basis of the amount of the hydro-cracked lubricating base oil.
