ABSTRACT:
Gasoline compositions and additive mixtures containing compounds having the formula: ##STR1## wherein R.sub.1 -R.sub.6 are each independently selected from hydrogen or hydrocarbyl radicals in an amount sufficient to reduce exhaust hydrocarbon emissions from an internal combustion engine being operated on gasoline containing a cyclopentadienyl manganese antiknock. Preferred hydrocarbon exhaust emission reducing compounds are 1,3-dioxolane and the lower alkyl and alkenyl substituted derivatives thereof.
