A high performance methanol fuel is described. In the present invention, the methanol fuel is formulated with approximately 3-15% high purity water, resulting in an aqueous fuel whose properties are independent of subsequent condensation of water from the environment. A low concentration dye, in the range of 0.0005 to 0.0020 weight percent, is utilized to impart color to the liquid fuel. In the preferred embodiment, arazine yellow, manufactured by Chem Serv is utilized, and has no noticable effect on fuel properties. A low concentration of alkali metal salts, such as sodium or lithium carbonate, or a low concentration of alkaline earth salts such as calcium or strontium acetate, in the range of 0.0005 to 0.001 weight percent is utilized as a flame colorant. Improved lubricity of the methanol fuel of the present invention is achieved by utilizing a flourosurfactant of about 0.05 percent by weight. In the preferred embodiment, ZONYL manufactured by DUPONT, is utilized. In order to test the effectiveness of the lubricating additive, a simple test in which an electric motor driven pump is used to maintain a constant flow rate of a fuel containing lubricating agent is performed. By measuring the wattage required to maintain the constant pumping rate for a variety of fuels containing different percentages and different compositions of lubricating agents, meaningful comparisons can be achieved.
