The invention belongs to the technical field of fuels and particularly relates to a multifunctional methanol fuel, prepared from, by weight, 60-90 parts of methanol, 20-44 parts of gasoline, 1-7 parts of 3-tert-butyl-4-hydroxyanisole, 0.5-2.3 parts of ethyl levulinate, 0.5-2.3 parts of 4-tert-butyl-2,6-diisopropylphenol, 0.4-2.2 parts of polyvinyl alcohol, 0.2-1.4 parts of dimethyl carbonate, 0.2-1.4 parts of a clearing agent, 0.1-1.3 parts of a corrosion inhibitor, 0.03-0.21 part of dicycloheptadiene, and 0.02-0.2 part of glyceryl monostearate. The multifunctional methanol fuel has the functions, such as clearing, anti-oxidation, combustion supporting, corrosion inhibition and detonation resisting, has good combustion performance, and can combust fully such that energy is saved and emission is reduced.
