Ethanol is the leading cause of failure in all internal combustion engines especially antique cars and trucks and marine engines that employ carburators. It eats away at the softer metals that are within the intake systems of these engines costing thousands of dollars in unnecessary repair bills.
Not to mention its energy content is only 80% of gasoline, and without government subsidies it's actual production cost would be around $5.00 a gallon.
Meaning that it makes each gallon of gasoline less efficient, destructive to your engine, and more expensive at the pump.
Lets spend our tax dollars on alternative energy that makes sense.
Try running hydrogen in our combustion engines, it's more efficient, its a great way to store and use wind and solar energy, and it's exhaust is water.
