    Abstract: 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.

    Abstract: An aviation gasoline composition comprising an impure iso-octane fraction, at least one xylene and at least one C4 or C5 alkane, wherein the impure iso-octane fraction in said composition is a fraction comprising at least 90 mol % iso-octane and having a final boiling point of at least 180° C. and is present in the composition in an amount in the range of from 30 to 80 vol. % based on the composition, the composition is substantially free of any lead compounds, the composition has a motor octane number of at least 94 and the composition has a final boiling point of at most 170° C. The composition of the present invention may be made by blending together an impure iso-octane fraction, xylene, at least one C4 or C5 alkane, optionally ethyl tertiary butyl ether, and optionally methylcyclopentadienyl manganese tricarbonyl and may be used in a spark ignition aviation engine, either alone or in combination with methanol or a methanol and water mixture.
