Re fuel consumption, you can use as low as 160-proof, 180-proof is said to be a better fuel anyway, and if you use an injection system it can burn up to 50% water, with other benefits too - for instance, that engines with an injection system still retain complete dual fuel capability, and alcohol injection can be used with fuel-injected, turbocharged, and even diesel engines.
