Alcohol is also very hard on carb and/or injector parts. Its natural tendency to draw moisture makes it tough on
steel carb internals. Most racers running on methanol start the engine on gas and then switch over. Conversely,
you have to run gas to clean the system before shutting down or completely drain and lubricate. Wouldn't be my
first choice for fuel at 20 F or below. Tough enough to keep moisture out as it is.
