Abstract (en)

[origin: WO2017157892A1] The present application relates to a lubricant composition comprising: - an oil selected from among polyalkylene glycols (PAG); and - a wear-resistant additive selected from among the compounds of formula (I) where R1 and R2 are identical or different and independently represent a linear or branched secondary alkyl group containing 2 to 7 carbon atoms, preferably 3 to 6 carbon atoms. Said lubricant composition is particularly useful for lubricating a vehicle engine, preferably a motor vehicle engine.
