The present disclosure relates to a lubricating fluid for an electric motor system and a method of lubricating gears and cooling a motor in an electric motor system. In particular, the disclosed technology relates to a lubricating fluid, for use in electric motor vehicle, comprising an oil of lubricating viscosity and at least one phosphorylated dispersant exhibiting increased resistivity after aging.

Phosphorylated dispersants in fluids for electric vehicles

The present disclosure relates to a durable lubricating fluid for an electric motor or hybrid-electric motor. The disclosed technology relates to a durable lubricating fluid comprising an oil of lubricating viscosity, a thiadiazole or derivative thereof, and an amine salt of a phosphoric acid.

Durable lubricating fluids for electric vehicles

A lubricant composition, a method for improving lubrication and a method for lubricating a machine. The lubricant composition includes a) a major amount of a base oil having a kinematic viscosity between 2 and 4 cSt at 100&#xb0; C.; and b) dioctyl phosphite in an amount providing from about 100 to about 1000 ppm phosphorus to the lubricant composition. The lubricant composition has a phosphorus weight ratio of component (b) to total phosphorus in the lubricant composition of from 0.4:1 to less than about 0.8:1.

Low viscosity transmission fluids with enhanced gear fatigue and frictional performance

A lubricant composition, a multi-vehicle transmission fluid, and a method for making a transmission fluid. The lubricant composition includes a) a base oil; b) 2,5-dimercapto-1,3,4-thiadiazole (DMTD), a derivative of DMTD, or mixtures thereof; and c) a friction modifier. The friction modifier is made by reacting an olefin containing at least 40% by weight C-Cvinylidene olefin with maleic acid, anhydride, or ester to provide a first reaction product, and aminating the first reaction product with an effective amount of a compound containing basic nitrogen to provide the friction modifier. The C-Cvinylidene olefin is represented by the following formula: wherein Rand Rare independently a (C-C) alkyl, cycloalkyl or cycloalkenyl.
