M5 is simply the best performing methanol on the market. With its upgraded combustion additives, M5 will make more power than standard methanol, while offering the same or better protection against detonation. M5’s improved vaporisation offers a wider acceptable range of air/fuel ratios and tuning, as well as faster combustion speeds.
M5 is not pure methanol and won’t pass a water test.
Ethanol %: 0%
Oxygenates %: 48.13%
Note: The octane ratings for methanol fuels are estimates. The convetional ASTM laboratory octane tests cannot accommodate the high oxygen content of methanol fuels.
