Abstract
LUBRICANT COMPOSITIONThis invention provides a lubricating oil composition suitable for use in an electric vehicle, comprising:a base oil comprising Fischer-Tropsch derived base oils,poly-α-olefin base oils or mixtures thereof; and in the range of from 0.5 to 12wt% of a friction modifier additive,wherein the friction modifier additive is a compound of formula (I) R<sup>1</sup>[(AO)<sub>n</sub>-R<sup>2</sup>]<sub>m</sub> (I)wherein:R<sup>1</sup> is the residue of a group having at least 2 active hydrogen atoms; m is at least 2;AO is an alkylene oxide residue; each n is independently from 0 to 100; and each R<sup>2</sup> is independently H or R<sup>3</sup>, where each R<sup>3</sup> is independently a residue of a polyhydroxyalkyl or polyhydroxyalkenyl carboxylic acid, a residue of a hydroxyalkyl or hydroxyalkenyl carboxylic acid and/or a residue of an oligomer of the hydroxyalkyl or hydroxyalkenyl carboxylic acid; and on average at least 0.5 of R<sup>2</sup> groups are R<sup>3</sup>,wherein the lubricating oil composition has a kinematic viscosity at 100°C in the range of from 2.0 to 5.5 cSt.
