High percentages of ethanol can be used but as said, producing it takes some doing. The carbon balance when it's from corn starch is poor but from sugar cane is good - US use corn, Brazil use cane and have been for many years, but then they have very few people for the amount of land they have. Not sure about wheat, that'll be what a lot of ours is. You don't get many mpg though, and really you need an engine designed for it as it has a high octane number, so you want the extra compression to make it all worthwhile, and the combustion products are acidic so at high levels they can't be ignored (as in Brazil).

A Bibio says I suspect this will all be a storm in a teacup although the papers and the likes of MCN are no doubt wailing about it. Headlines and facts however make poor bedfellows so it's bull**** season.
