The lubricating oil composition comprises 15-85 parts by weight of a poly-.alpha.-olefin having a kinematic viscosity of 1.5150 centistokes at 100.degree.C and 85-15 parts by weight of a mineral oil having a kinematic viscosity of 2-50 centistokes at 100.degree.C and a pour point of -35.degree.C or below. By virtue of the admixture of the mineral oil, the lubricant oil composition is much more inexpensive than the poly-.alpha.-olefin per se while retaining the excellent properties inherent in the poly-.alpha.-olefins such as the stability against oxidation, low-temperature performance, high-temperature cleanness and friction characteristics with wet clutches. |
