Abstract
Abstract This invention relates to a polyether amino amide additive and to a motor fuel composition containing same which inhibits ORI and has good carburetor detergency properties. The additive is represented by the formula: ##STR1## in which R is a hydrocarbyl radical having from 6 to 18 carbon atoms, m is a integer from 2 to 4, R' is divalent alkylene radical having from 2 to 3 carbon atoms, n is 1 or 2, and X is a radical from the group consisting of: ##STR2## The present invention is also directed to a gasoline motor fuel composition having a reduced ORI and good carburetor detergency properties which composition contains a minor account of at least one of the above compounds.
