A process for preparing amide alkoxylates. More specifically, the invention provides a butoxylation process for producing poly(oxyalkylene) amides and poly(oxyalkylene) esters via an exchange reaction of (trans-amidation/trans-esterification) and involving removal of the poly(oxyalkylene) esters in the product mixtures so that a better performance products can be obtained. The invention further relates to the use of these compounds as fuel additives to decrease intake valve deposits, positively affecting the engine's octane requirement, control the increase of combustion chamber deposits and improve fuel quality. The invention further discloses a composition used as engine fuel, characterized in that it contains said poly(oxyalkylene)amide as the fuel additive.
