Zusammenfassung:PURPOSE: Multiple amide polyether alcohol compounds as additives of fuel compositions are provided which decrease intake valve deposits when used as gasoline additives. CONSTITUTION: A multiple amide polyether alcohol compounds are represented by formula (I), wherein R1 and R2 are each independently selected from the group consisting of hydrocarbyl of 1 to 100 carbon atoms and substituted hydrocarbyl of 1 to 100 carbon atoms; R3 and R4 are each independently selected from the group consisting of hydrocarbyl of 1 to 100 carbon atoms, substituted hydrocarbyl of 1 to 100 carbon atoms and polyoxyalkylene alcohol of 2 to 200 carbon atoms; R5 is selected from the group consisting of alkylene of 2 to 20 carbon atoms and alkylene of 2 to 20 carbon atoms having at least one methylene group replaced by at least one oxygen atom or at least one acylated nitrogen atom; x and y are each from 1 to 50 and the weight average molecular weight of the additive compound is greater than about 600.
