The article goes on to explain that ethanol has its own laundry list of issues. However, the simple truth is that lead was added to gas to prevent engine knock. Lead was determined to be harmful, and was replaced by MTBE. It was also found to be harmful, and was replaced by ethanol.
This may be the historical progression of gasoline additives, but I'm pretty sure that ethanol actually has nothing to do with preventing engine knock. I thought auto makers simply found ways to design engines that didn't require such an additive.
As I understand it, it was only through lobbying efforts of "big corn" that they were able to slip in ethanol as an additive in the place of lead, but that there is no useful purpose at all for car engines for the actual addition of ethanol. It really has nothing at all to do with "market" forces in the traditional sense of that word.
Correct me if I'm wrong, as I don't proclaim to be an expert on this subject, just an interested observer/consumer.

That's a good question. I have a toxicology back ground. Not a Chem-E background. However everything I have always read was that ethanol is used for anti knocking.
