Abstract
This invention provides a fuel composition having a sulphur content of not more than 50 ppm by weight and comprising at least 50 ppm based on the total weight of the fuel composition of at least one fused polycyclic aromatic compound which comprises at least one exocyclic group containing nitrogen wherein the nitrogen is attached directly to a ring carbon atom. Specific examples of such compounds include 1-amino naphthalene, 1,8-diaminonaphthalene, or 5-aminoindole, 2-(2-aminophenyl)indole and 8-aminoquinoline. These compounds are capable of improving the antiwear and lubricity properties of a low sulphur fuel when compared with that of the same fuel in the absence of such compounds.
