We formulate VP M5 fuel to be the best performing methanol on the market. M5 makes more power than standard methanol because of its upgraded combustion additives. Furthermore, it offers the same or better protection against detonation. VP M5 has improved vaporization. As a result, it offers a wider acceptable range of air/fuel ratios and tuning, as well as faster combustion speeds. M5 fuel is designed for both drag racing and circle track racing. It is not pure methanol and won’t pass a water test. Are you looking to improve your engine's performance? Check out VP's wide line of racing motor oil and engine lubricants.
