Abstract: A fuel additive package is disclosed that prevents degradation of hydrocarbon fuels upon storage and permits extended use of such motor fuels without intake-valve deposit formation in vehicle motors. The additive contains an antioxidant, metal deactivator, corrosion inhibitor, and detergent. The corrosion inhibitor, preferably a carboxylic acid containing a carbon number equal to or less than 18 and the detergent component, preferably a polyisobutylene diamine are selected to avoid antagonistic effects with the antioxidant and metal deactivator components while the antioxidant and metal deactivator components are used in markedly reduced amounts to avoid antagonistic effects resulting in increased intake-valve deposits.
