Abstract: An axle lubricating oil composition includes a polyalphaolefin having a kinematic viscosity at 100° C. of from 2 to 40 cSt when measured in accordance with ASTM D445. The axle lubricating oil composition also includes an alkoxylated polytetrahydrofuran of general formula (II). The alkoxylated polytetrahydrofuran of general formula (II) is present in an amount of from 10 to 40 parts by weight based on 100 parts by weight of the axle lubricating oil composition.

Abstract: A lubricant composition includes a polyalkylene glycol base oil component in an amount of at least about 60 parts by weight based on 100 parts by weight of the lubricant composition. The lubricant composition has a kinematic viscosity at 100° C. of from about 4 to about 50 cSt and a kinematic viscosity at 40° C. of from about 20 to about 700 cSt, each measured in accordance with ASTM D445.
