    Abstract: Multiple amide polyether alcohol compounds of the formula: ##STR1## wherein R.sub.1 and R.sub.2 are each independently selected from the group consisting of hydrocarbyl of 2 to 100 carbon atoms and substituted hydrocarbyl of 2 to 100 carbon atoms; R.sub.3 and R.sub.4 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; R.sub.5 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 when used as gasoline additives are found to decrease intake valve deposits.
