ABSTRACT:
The present invention provides an additive for improving the lubricity of fuel oils having a maximum sulfur content of 0.035% by weight. The additive comprisesA) at least one partial ester composed of a di- or polyhydric alcohol and unsaturated and optionally also saturated fatty acids whose carbon chain lengths are between 8 and 30 carbon atoms, at least 60% of the fatty acid radicals containing at least one double bond, andB) at least one alkylphenol-aldehyde resin, obtainable by the condensation of(i) at least one alkylphenol having at least one C6-C24-alkyl or C6-C24-alkenyl radical and(ii) at least one aldehyde or ketone,to a degree of condensation of between 2 and 50 alkylphenol units.
