Interesting. I do like the idea of using colouring for the water, makes it much easier. I wonder how much octane rating you lose. I do know at least one person who does this regularly. Such a pain to pay all that money for 10% that you are just going to remove and chuck away. Or perhaps a still is in order, now what could I do with some pure ethanol?
Does anyone know any others who have done this?
Cheers, Richard.
