Methanol gasoline is added to the methanol partial gasoline cosolvent with methanol fuel, the fuel mix of the compound M Series. Of which: M15 (15% methanol) clean methanol gasoline vehicle fuel, were used in a variety of gasoline engines, can not change the existing conditions of the engine structure, replacing the use of finished gasoline, gasoline and refined oil mix . The thermal efficiency of methanol blended fuel, power, start, good economy, reduce emissions, save oil, safe and convenient. Countries in the world according to different national conditions, research and development of the M3, M5, M15, M20, M50, M85, M100 and other different blending ratio of methanol fuel. Commercial methanol for M85 (85% methanol and 15% gasoline) and M100, M100 performance better than the M85, has a greater environmental superiority.
