Abstract

See full text

Disclosed is a composition of continuously variable transmission oil for improving fuel efficiency and endurance performance. Provided herein is a novel composition of continuously variable transmission oil that can improve fuel efficiency through reduction of fluid resistance by decreasing viscosity at a low temperature, and can enhance endurance performance of the transmission by increasing the viscosity at a high temperature. Provided herein is a continuously variable transmission oil composition containing a predetermined amount of olefin amide comb PMA as a viscosity adjusting agent in a base oil having a pour point of −40° C. or less, in addition to additives.
