Chisa- It's already cheaper to get a 260 litre drum of Methanol delivered which you keep in the garage and top the tank off as required.
Higher octane (significantly higher) than pump fuel, also.
If the price of pump fuel keeps going up I think we'll see more "alternative" fuels, and of course the government chasing after them in search of tax revenue.
How much is 260L of methanol?
Quite a few people have been doing alt fuels for years.
