Abstract (en)
[origin: EP0340302A1] A lubricating oil composition for gear which contains as a base oil polyoxyalkylene glycol ester obtained by reacting a polymer prepared by ring-opening polymerisation or ring-opening copolymerization of one or more members selected from among alkylene oxides having 2 to 4 carbon atoms with a carboxylic acid having 1 to 10 carbon atoms. This lubricating oil composition has remarkably good oxidation stability and abrasion resistance at high temperatures and flowability at low temperatures.
