Abstract: A composition useful as a gasoline additive, preferably to increase engine performance and/or mileage per unit volume of fuel, is described. The composition comprises about 45% to about 55% by weight of toluene and about 45% to about 55% by weight of C.sub.8 alkyl aromatic component selected from the group consisting of ethylbenzene, paraxylene, metaxylene, orthoxylene and mixtures thereof.

Abstract: A composition and process for cleaning an aluminum-containing article is disclosed. The process comprises contacting a debris-laden aluminum-containing article with a composition at conditions effective to do at least one of the following: (1) remove at least a portion of the debris from the aluminum-containing article and (2) condition at least a portion of the debris for removal from the aluminum-containing article. The composition comprises water; at least one polycarboxylic acid component selected from the group consisting of polycarboxylic acids, salts of polycarboxylic acids and mixtures thereof; at least one acidic component in an amount effective to increase the solubility of the polycarboxylic acid component in the composition; and at least one acid acting enzyme in an amount effective to at least facilitate the removal of debris from an aluminum-containing article contacted with the composition.
