Abstract (en)
[origin: WO2022228988A1] The invention provides a lubricating oil composition comprising: (a) from 45 to 75 mass% of a low viscosity first base oil component which is a Fischer-Tropsch derived base oil with a kinematic viscosity at 100°C in the range of from 3.5 to 7.0 mm2/s; (b) from 3 to 35 mass% of a high viscosity second base oil component which is a polyalkylene glycol; (c) an anti-foam additive which is a non-ionic surfactant, wherein mass% is based on the overall mass of the lubricating composition.The present invention also provides a method for lubricating an axle, said method comprising supplying to said axle a lubricating oil composition comprising:(a) from 45 to 75 mass% of a low viscosity first base oil component which is a Fischer-Tropsch derived base oil with a kinematic viscosity at 100°C in the range of from 3.5 to 7.0 mm2/s; (b) from 3 to 35 mass% of a high viscosity second base oil component which is a polyalkylene glycol; (c) an anti-foam additive which is a non-ionic surfactant, wherein mass% is based on the overall mass of the lubricating composition.
