NOVELTY - Preparing an ethanol fuel composition, comprises: (a) providing a first amount of ethanol to vessel; (b) adding ethoxylated oleyl amine and ignition improver to ethanol to obtain a first mixture, where in first mixture, the ethanol is present at 35-55 wt/wt.%, and weight ratio of ethoxylated oleyl amine to ethanol is 1:4-1:15, preferably 1:6-1:10; (c) blending first mixture by using vertical circulation and/or stirring, so that a blended first mixture is obtained; (d) combining blended first mixture with a second amount of ethanol to obtain second mixture; and (e) blending the second mixture.    USE - The method is useful for preparing an ethanol fuel composition (claimed), which is useful in diesel engines.    ADVANTAGE - The method: reduces or avoids precipitation of components of the ethanol fuel composition; and can be carried out using less costly equipment, as compared to conventional methods.    DETAILED DESCRIPTION - Preparing an ethanol fuel composition, comprises: (a) providing a first amount of ethanol to a vessel; (b) adding an ethoxylated oleyl amine and an ignition improver to the ethanol to obtain a first mixture, where in the first mixture, the ethanol is present at 35-55 wt/wt.%, a weight ratio of ethoxylated oleyl amine to ethanol is 1:4-1:15, preferably 1:6-1:10, and a weight ratio of ignition improver to ethanol is 1:1-1:3, preferably 1:1.2-1:2; (c) blending the first mixture by using vertical circulation and/or stirring, so that a blended first mixture is obtained; (d) combining the blended first mixture with a second amount of ethanol to obtain a second mixture; and (e) blending the second mixture to obtain the ethanol fuel comprising 80-90 wt/wt.%, preferably 84-88 wt/wt.% ethanol, 0.1-2 wt/wt.%, preferably 0.5-1.5 wt/wt.% ethoxylated oleyl amine, and 3-10 wt/wt.%, preferably 4-6 wt/wt.% ignition improver. The ignition improver is a water soluble adduct of polyol having 3-10 hydroxy groups and ethylene oxide and/or propylene oxide, where a molecular weight of the adduct is 350-2000 Da, preferably 600-1000 Da.
