11 Things You Need To Know About Water/Methanol …

Both methanol and ethanol burn at lower temperatures than gasoline and both are less volatile, making the engine starting in cold weather more difficult. Using methanol as a fuel in spark-ignition engines can offer increased thermal efficiency and increased power output (as compared to gasoline) due to its high octane rating (114 ) and high heat of vaporization.
