Disclosed is a lubricant additive capable of providing an antioxidant which enables a lubricant composition to have long drain intervals, while reducing specific components such as metal contents and phosphorus atoms. Also disclosed is a lubricant composition containing such a lubricant additive. Specifically disclosed is a phosphorus-molybdenum compound represented by the following general formula (I) where R1, R2 and R3 independently represent a hydrocarbon group having 1-20 carbon atoms.
La présente invention concerne un additif pour lubrifiant capable de constituer un antioxydant qui permet à la composition de lubrifiant de prolonger les intervalles entre vidanges, tout en réduisant des composants spécifiques tels que le métal contenu et les atomes de phosphore. L'invention concerne également une composition de lubrifiant contenant un tel additif pour lubrifiant. L'invention concerne plus spécifiquement un composé de phosphore et de molybdène représenté par la formule générale suivante (I) dans laquelle R1, R2 et R3 sont indépendamment des groupes hydrocarbure en C1-C20.
