A lubricating composition includes at least one base oil, at least one borated dispersant, at least two antioxidants selected from amine antioxidants, phenolic antioxidants substituted with one or more linear or branched alkyl groups having from 1 to 30 carbon atoms, and mixtures thereof, and at least one phosphite polymer having the formula (I) wherein: —each of the R, R, Rand Rcan be independently selected from the C1-C20 alkyl, C3-C22 alkenyl, C6-C40 cycloalkyl, C7-C40 cycloalkenyl, C1-20 methoxy alkyl glycol ethers and Y—OH groups; —Y is selected from C2-C40 alkylene, C2-C40 alkyl lactone, —R—N(R)—R— groups, in which R, Rand Rare independently selected from hydrogen, C1-C20 alkyl, C3-C22 alkenyi, C6-C40 cycloalkyl, C7-C40 cycloalkenyl, C1-20 methoxy alkyl glycol ethers; —m is an integer from 2 to 100; —n is an integer from 1 to 1000.

Lubricant composition for oxidation-stable automotive transmission

The present invention concerns the use of at least one polyorganosiloxane to release air from a lubricant composition comprising at least one base oil, when lubricating at least one moving part of an electric or hybrid vehicle.

Deaeration of a lubricant composition

The invention relates to the use of at least one triazole compound as an additive for improving the anti-corrosion properties of a lubricant composition for a propulsion system of an electric or hybrid vehicle, said lubricant composition comprising one or more amino and/or sulfur anti-wear additives. The invention also relates to the use of a lubricant composition for lubricating a propulsion system of an electric or hybrid vehicle.
