CA 2230125

A low emissions, high oxidative stability crankcase lubricating oil formulation which is prepared from a base stock which comprises at least one synthetic ester selected from the group consisting of: polyol esters, synthetic esters having between 5-35 % unconverted hydroxyl groups, based on the total amount of hydroxyl groups in the polyol, and synthetic esters combined with at least one additional functional group which is capable of increasing the polarity of the functionalized synthetic ester, wherein the base stock has an oxygen, nitrogen or halogen content of at least 15 wt.%, based on the total weight of the base stock; and a lubricant additive package.

Cette invention concerne une formulation d'huile lubrifiante de carter, à faible émission et d'un grande stabilité sur le plan de l'oxydation, laquelle formulation est préparée à partir d'un mélange de base comprenant au moins un ester synthétique choisi dans le groupe comprenant les éléments suivants: des esters de polyol; des esters synthétiques possédant de 5 à 35 % de groupes hydroxyle non convertis par rapport à la quantité totale de groupes hydroxyle dans le polyol; et, enfin, des esters synthétiques combinés à au moins un groupe fonctionnel additionnel capable d'accroître la polarité de l'ester synthétique fonctionnalisé. Le mélange de base possède un contenu en oxygène, azote ou halogène d'au moins 15 % en poids par rapport à son poids total. Cette invention concerne un emballage pour additif lubrifiant.
