Abstract: Disclosed is a lubricant composition including: an oil chosen from polyalkyl glycols (PAG or polyalkylene glycols); and an anti-wear additive chosen from compounds of formula (I) in which R1 and R2, which may be identical or different, independently represent a linear or branched secondary alkyl group including from 2 to 7 carbon atoms, preferably from 3 to carbon atoms. This lubricant composition is particularly useful for the lubrication of a vehicle engine, preferably of a motor vehicle.
