    摘要： A lubricity additive for fuels with sulphur content of not more than 0.05 wt % is described herein. The lubricity additive comprises a polyol ester or a mixture of polyol esters derived from C8-C18 saturated and/or unsaturated fatty acids. The polyol esters is produced by: i) esterification of a C8-C18 saturated or unsaturated fatty acids, or a mixture thereof, with a polyhydric alcohol; ii) transesterification of an oil or a mixture of oils, with fatty acid composition comprising C8-C18 saturated and/or unsaturated fatty acids, with a polyhydric alcohol. The preferred fatty acids are unsaturated C18 fatty acids, more particularly, oleic acid whereas the preferred polyhydric alcohol is neopolyol, more particularly, trimethylol propane and its isomers. A fuel composition comprising a major amount of fuel with sulphur content of not more than 0.05 wt % and a minor amount of the lubricity additive is also described herein. The amount of the lubricity additive is not more than 0.1 wt %.
