    Abstract: An improved detergent for use in hydrocarbon fuels comprising the composition produced by mixing (1) the Mannich reaction product of a polyisobutene-substituted phenol, (preferably, where the polyisobutene from which the substituted phenol is derived contains at least 70% terminal olefinic double bonds of the vinylidene type); an aldehyde; and an amine, preferably, ethylene diamine; and (2) a compound selected from the group consisting of an alkylbenzene sulfonic acid, an alkylnapthalene sulfonic acid, acetylaetone and mixtures thereof. Preferably, the alkylbenzene and alkylnapthalene sulfonic acid is selected to be a (C6 to C18) alkylbenzene sulfonic acid/napthalene sulfonic acid, especially preferred being dodecylbenzene sulfonic acid.

    Abstract: The present invention is directed to fuel additive compositions of detergents combined with fluidizers and to hydrocarbon fuel compositions containing these fuel additive compositions. The fuel additive compositions of the present invention combine a Mannich detergent, formed from reaction of an alkylphenol with an aldehyde and an amine, with a fluidizer that can be a polyetheramine or a polyether or a mixture thereof and, optionally, with a succinimide detergent. Fuel compositions containing these fuel additive compositions are very effective in reducing intake valve deposits in gasoline fueled engines, especially when the weight ratio of detergent(s) to fluidizer(s) is about 1:1 on an actives basis.
