Ethanol is still being used as an Octane booster, last year (IIRC) the midwest pipe lines switched frome being 87 octane to 85, without 10% ethanol or premium mixed in, their (big oil) base fuel is not marketable. E10 burns cleaner is about 5% cheaper than 87 octane E0, but only 1.5% lower BTU's per gallon though studies in the link above show that btu's/ gallon doesn't = btus/mile.
Big oil came up with the food vs fuel lie and have been running with it for years. Petrolumn had a greater influence on food cost than ethanol.
How Oil Prices Affect the Price of Food
I didn't even read it, it was just second article that came up googling "petrolum vs food" the graph provides all the data food cost follows petrolum.
