Title (EN) LUBRICATING OIL COMPOSITIONS
(FR) COMPOSITIONS D'HUILES LUBRIFIANTES
Abstract:
(EN) A lubricating oil composition having a sulfur content of up to about 0.4 wt. % and a sulfated ash content of up to about 0.5 wt. % as determined by ASTM D874 is disclosed which comprises (a) a major amount of an oil of lubricating viscosity; (b) at least one oil-soluble or dispersed oil-stable boron-containing compound having no more than about 400 ppm of boron; and (c) at least one oil-soluble or dispersed oil-stable molybdenum-containing compound having at least about 1100 ppm of molybdenum, based upon the total mass of the composition; wherein the lubricating oil composition has a ratio of sulfur to molybdenum of less than or equal to about 4:1.
(FR) L'invention concerne une composition d'huile lubrifiante dont la teneur en soufre s'élève jusqu'à environ 0,4 % en poids, et la teneur en cendre sulfatée jusqu'à environ 0,5 % en poids, selon la norme ASTM D874. La composition comprend (a) une quantité majeure d'une huile de viscosité lubrifiante; (b) au moins un composé contenant du bore soluble dans l'huile ou stable dans l'huile dispersée n'ayant pas plus d'environ 400 ppm de bore, et (c) au moins un composé contenant du molybdène soluble dans l'huile ou stable dans l'huile dispersée ayant au moins environ 1100 ppm de molybdène, sur la base de la masse totale de la composition. La composition d'huile lubrifiante de l'invention a un rapport de soufre au molybdène inférieur ou égal à environ 4:1.
