Abstract

Una composicion de aceite lubricante que comprende una cantidad principal de un aceite de viscosidad lubricante y una cantidad menor, soluble en aceite odispersable en aceite, de (a) un compuesto de organomolibdeno trinuclear, (b) un compuesto de az ufre, (c) un antioxidante fenolico y (d) un antioxidanteamínico, tal que el compuesto de azufre (b) sea un hidrocarbil éster o ácido tiodicarboxílico; y un método para mejorar la estabilidad de oxidacion de unacomposicion de aceites lubricantes. Las composiciones que comprenden los ingredientes de la presente invencion muestran una estabilidad de oxidacion por lejossuperior cuando se las comparan con aquellas que no contienen la combinacion de antioxidantes.A lubricating oil composition comprising a major amount of an oil of lubricating viscosity and a smaller, oil-soluble oil-dispersible amount of (a) a trinuclear organomolibdene compound, (b) a sulfur compound, (c) a phenolic antioxidant and (d) an antioxidant, such that the sulfur compound (b) is a hydrocarbyl ester or thiodicarboxylic acid; and a method to improve the oxidation stability of a lubricating oil composition. The compositions comprising the ingredients of the present invention show a far higher oxidation stability when compared to those that do not contain the antioxidant combination.
