ABSTRACT:
Conductive fuel detergent compositions which posses not only the desirable characteristics of minimizing unwanted deposits on internal engine surface such as intake systems or port fuel injectors and exhibiting anticorrosion characteristics but also have conductive properties comprise quaternary succinimides which are characterized by having an oligomeric alkyl moiety on the succinimide ring. The additive may be prepared by condensing a (polyalkyl)succinic anhydride with a polyamino hydroxyalkyl quaternary ammonium salt, where the latter is formed by the reaction of a .OMEGA.-haloepoxide with a tertiary amine followed by reaction of the resulting product with a polyamine.
