Le procédé comprend une étape consistant à mélanger indépendamment avec un premier carburant, un agent anti-cliquetis, un agent anti-fumigation, un tensioactif non ionique, un agent lubrifiant, un agent de nettoyage, un spiritueux minéral, un antioxydant, un agent améliorant l'indice d'octane, un agent de stabilisation et un additif oxygéné, pour obtenir un mélange. Le mélange est agité pendant une durée allant de 15 minutes à 55 minutes pour obtenir un mélange homogène de la composition d'additif pour carburant. La composition d'additif pour carburant est mélangée avec un second carburant pour obtenir une composition de carburant. La composition d'additif pour carburant obtenue par le procédé selon la présente invention améliore l'efficacité de combustion de carburant tout en réduisant l'émission de gaz à effet de serre.
