| Summary: | An additive composition for use in a fuel for a spark-ignition internal combustion engine comprises an octane-boosting additive and one or more further fuel additives. The octane-boosting additive has a chemical structure comprising a 6-membered aromatic ring sharing two adjacent aromatic carbon atoms with a 6- or 7-membered saturated heterocyclic ring, the 6- or 7-membered saturated heterocyclic ring comprising a nitrogen atom directly bonded to one of the shared carbon atoms to form a secondary amine and an atom selected from oxygen or nitrogen directly bonded to the other shared carbon atom, the remaining atoms in the 6- or 7-membered heterocyclic ring being carbon. The additive composition increases the octane number of the fuel, thereby improving the auto-ignition characteristics of a fuel. |
