ABSTRACT:
Exhaust hydrocarbon emissions of an internal combustion engine being operating on gasoline containing a cyclopentadienyl manganese antiknock are reduced by the addition of a dimer or a trimer acid or mixture of a dimer and a trimer acid produced by the polymerization or condensation of an unsaturated aliphatic monocarboxylic acid having between 16 and 18 carbon atoms per molecule to the gasoline.
