Gasoline compositions and additive mixtures containing compounds having the formula ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3 are independently selected from hydrogen, hydrocarbyl radicals, and substituted hydrocarbyl radicals, and R.sub.4 is selected from hydrogen, hydrocarbyl radicals, substituted hydrocarbyl radicals, hydrocarbyloxy radicals, and hydrocarbyloxycarbonyl radicals, in an amount sufficient to alleviate the plugging of certain catalysts being used in an engine exhaust system to lower the amount of undesirable constituents in exhaust gas from an engine being operated on gasoline containing a cyclopentadienyl manganese antiknock.
