ABSTRACT The present invention provides a method for inhibiting corrosion and elastomer swelling and degradation caused by alcohol and alcohol-containing fuels and for increasing lubricity of alcohol or alcohol-containing fuels, comprising the step of adding to alcohol or alcohol-containing fuels, a fuel additive comprising one or more reaction products of a carboxylic acid or acid chloride selected from the group consisting of unsubstituted aromatic carboxylic acids, aliphatic carboxylic acids, nitro-substituted aromatic carboxylic acids and their corresponding acid chlorides, and an amine selected from the group consisting of aliphatic amines, cycloaliphatic amines, and aromatic amines. The present invention also provides a fuel composition for internal combustion engines, comprising: (a) a major portion of fuel comprising from about 1 to 100% by volume of an alcohol having 1 to 4 carbon atoms and from about 99 to 0% by volume of a non-alcohol fuel selected from the group consisting of gasoline, individual hydro- carbon components of gasoline, and dimethoxymethane, and (b) a minor portion of the fuel additive described above.
