Well fuel air ratio is half as much for methanol, meaning about twice as much fuel to air. But then the displacement is changed so there is actually less air being induced in the engine and to a lesser factor the fuel as well. Now consider that you will need about 30 to 50% more displacement, and thus more gas to have the same power and the difference is not nearly twice as much fuel used. But if using nitro it will be twice as much or more.
