Abstract:
The present invention relates to a lubricating oil composition comprising polyglycerol partial esters of polyfunctional carboxylic acids and saturated or unsaturated, linear or branched fatty acids and/or poly(hydroxystearic acid) and the use thereof to lubricate an engine and reduce friction.

Claim (Index 1):
A lubricating oil composition comprising\n (a) 0.2 to 5% by weight of one or more polyglycerol partial esters, based on a total weight of the lubricating oil composition, wherein the polyglycerol partial esters are obtained by esterification of a polyglycerol mixture with (i) one or more polyfunctional carboxylic acids and (ii) one or more saturated or unsaturated, linear or branched fatty acids and/or (ii) poly(hydroxystearic acid), wherein a degree of esterification of the poly-glycerol mixture is between 30 and 75% of the OH goups; (b) 85 to 99.8% by weight of an apolar base stock selected from the group consisting of API Group II, III and IV and mixtures thereof, based on the total weight of the lubricating oil composition; and (c) 0 to 10% by weight of a polar ester oil of API Group V, based on the total weight of the lubricating oil composition.
