The invention provides a vehicle-used methanol gasoline clean fuel, which not only comprises methanol, but also ethanol and additive so as to form a methanol and ethanol gasoline clean fuel. The clean fuel comprises low mixture ratio, medium mixture ratio and high mixture ratio in volume by weight. The invention also discloses a preparation method of the clean fuel: mixing the methanol, the ethanol, the addictive and the gasoline; according to three ratios, the steps are as follows: step 1, measuring the methanol and the ethanol and adding into a measuring cylinder; step 2, adding the addictive into the mixed liquid according to the mixture ratio, and stirring the mixture to be evenly mixed; and step 3, adding gasoline into the mixed liquid according to the mixed ratio, and stirring the mixed liquid again to be evenly mixed. The vehicle-used methanol gasoline clean fuel effectively improves the stability of mixed fuel, reduces the layering temperature of the system, makes up the defect that the methanol is limited by the raw materials by using rich methanol source, can be mixed according to three proportions, can ensure that the power performance is as same as the gasoline car, and obviously improves the pollutant emission.
