The invention relates to an 
oil additive and particularly discloses a 
methanol fuel additive and 
methanol gasoline prepared with the same. The 
methanol fuel additive comprises the following components in parts by weight: 15.9 to 20 parts of modifier, 8 to 12 parts of oxidant, 12 to 8 parts of activating agent, 15 to 17 parts of antiknock, 0.54 to 2.48 parts of 
cleaning agent, 40.5 to 34.5 parts of catalyst, 8 to 6 parts of 
corrosion inhibitor and 0.06 to 0.02 part of anti-attrition 
lubricant. According to the methanol 
gasoline prepared with the additive, methanol and 
gasoline can be completely soluble or instantly soluble after being mixed, so that the methanol gasoline is clear and bright in appearance, is not layered and is free from impurities; and the methanol gasoline has the characteristics of high 
octane value, stable burning, sufficient power and tiny contained 
colloid in running tests and examination, causes no 
corrosion and swelling reaction on materials of the conventional gasoline car, and can be mixed with unleaded gasoline for use or directly used on the premise of not changing an engine and an 
oil supply system of the conventional gasoline car.
