Can methanol be added to gasoline?
2 Answers
Methanol cannot be directly added to gasoline. Mixing methanol and gasoline will cause layering, and methanol gasoline additives are required to make methanol and standard gasoline mutually soluble, forming methanol gasoline, which can then be used in vehicles. Methanol gasoline additive solubilization technology: enhances stability, enables alcohol and oil to dissolve organically without layering or emulsification, and is mutually soluble with standard gasoline and ethanol gasoline. Water resistance: can resist moisture absorbed from the air during transportation, storage, and refueling. Corrosion resistance: through the strong interaction of alkaline groups in corrosion inhibitor molecules with metal surfaces, chemical and physical adsorption occurs, forming a protective film that isolates methanol from metal parts to a certain extent, achieving the purpose of reducing or inhibiting corrosion. Temperature adaptability: can be normally produced and used in environments ranging from -40°C to 40°C, resistant to low-temperature phase separation, easy to start at low temperatures, and free from vapor lock at high temperatures. Swelling inhibition: can protect non-metal components other than the corrosion-resistant metal parts, mainly fuel pumps, rubber seals (pipes), fuel distributors, and other fuel supply components, such as plastic and rubber parts.
Methanol can indeed be added to gasoline. I've been into cars for years and know that something like M85 is a methanol-gasoline blend. However, randomly adding methanol to a regular car can cause issues. Methanol is highly corrosive and can damage rubber hoses and seals in the fuel system, leading to leaks or blockages. The engine requires special tuning; otherwise, it may experience ignition difficulties or even engine seizure. FlexFuel vehicles are compatible with these blends, so it's best to check your manual or modify supporting components. Before use, you must choose dedicated material fittings, and cold starts in winter can be problematic. Don't ruin your car just to save a few bucks—consult a professional shop for safe modification methods.
