<p>A gear oil composition containing polyoxyalkylene glycol as a base oil, wherein the polyoxyalkylene glycol is a polymer obtained by ring-opening polymerization or ring-opening copolymerization of one or more members selected from among alkylene oxides having 2 to 4 carbon atoms and having a viscosity of 5 mm2/s to less than 20 mm2/s (at 100°C). This gear composition has remarkably excellent oxidation stability and abrasion resistance at elevated temperatures and a good flowability at low temperatures.</p> |
