Abstract (en)
The present invention relates to a lubricating oil composition for traction drive, which consists essentially of: (A) a base oil containing as the main component a saturated hydrocarbon or hydrocarbons having fused ring and/or nonfused ring, (B) an ethylene- alpha -olefin copolymer having a number-average molecular weight of 800 to 8,000, and (C) an anti-wear agent. The lubricating oil compositions of the present invention are effectively used in winter and cold districts, since they have a high coefficient of traction and show a limited change in the coefficient of traction at low temperatures.
