Claims19
A fuel composition for internal combustion engines comprising
- (a) a major portion of a fuel containing (i) at least one alcohol selected from the group consisting of ethanol and methanol and (ii) gasoline in amount of 0-50 volumes per volume of alcohol;
- and
- (b) a minor corrosion inhibiting amount of, as a corrosion inhibiting agent, a reaction product of (i) C.sub.15 -C.sub.30 hydrocarbyl succinic acid anhydride and (ii) aminotriazole.
A fuel composition for internal combustion engines comprising
- (a) a major portion of a fuel containing absolute ethanol;
- and
- (b) a minor corrosion inhibiting amount of, as a corrosion inhibiting agent, a reaction product of polyisobutenyl (M.sub.n of 300-3000) succinic acid anhydride and 3-aminotriazole.
The method which comprises adding to a fuel containing (i) at least one alcohol selected from the group consisting of ethanol and methanol and (ii) gasoline in amount of 0-50 volumes per volume of alcohol, a minor corrosion inhibiting amount of, as a corrosion inhibiting agent, a reaction product of (i) C.sub.15 -C.sub.30 hydrocarbyl succinic acid anhydride and (iii) aminotriazole.
