Abstract: This invention provides a novel synthetic fuel composition suitable for use in internal combustion engines. The fuel composition comprises from about 40 to 95% by volume of a primary alcohol having 1-4 carbon atoms, from about 5 to 60% by volume of an alcohol derivative having the general formula ##STR1## wherein R is --CH.sub.3, --C.sub.2 H.sub.5, --C.sub.3 H.sub.7, or --C.sub.4 H.sub.9, and R.sub.1 is hydrogen or --CH.sub.3.The fuel composition can be prepared by reacting a primary alcohol having 1-4 carbon atoms with oxygen or air to form an alcohol derivative which is an aldehyde and reacting the aldehyde with an additional portion of the alcohol to form the product, comprising the alcohol, the alcohol derivative and the aldehyde.
