ABSTRACT:
A method of operating a spark ignition internal combustion engine with unleaded gasoline is disclosed wherein methylcyclopentadienyl manganese tricarbonyl (MMT) is used as a primary antiknock compound and from about 5 to about 60 moles of benzoylacetone or methyl benzoylacetone per mole of manganese is used as a co-antiknock compound. These co-antiknock compounds are particularly suitable because they do not react with wet rusted steel in gasoline distribution systems, nor with terneplate surface coatings in automobile fuel storage tanks.
