    摘要： The present invention relates to an additive for improving the lubrication capacity of fuel oils with a maximum sulfur content of 0.035 wt. %. The additive contains at least one ester of a bivalent or polyvalent alcohol and a mixture of unsaturated and optionally saturated fatty acids, whose carbon chain lengths are between 8 and 30 carbon atoms, the aforementioned esters having an OH value of less than 200 mg KOH/g ester and an iodine value greater than 100 g l/100 g ester. The invention also relates to fuel oils with a maximum sulfur content of 0.035 wt. %, which contain the inventive additives. The novel additives exhibit less tendency to emulsify than the additives of the prior art.
