You just have to know how to count votes. Specifically, corn votes.
EPA 'allowed' it only for recent-vintage cars. Older ones, and small engines, should NOT use this stuff until 'further testing' is completed. And even then, use it at your own risk.
Note carefully the language used by
"Thorough testing has now shown that E15 does not harm emissions control equipment in newer cars and light trucks,"
Uh-huh. I worry about hoses, heads, gaskets, valves, and pistons, not about "emissions control equipment."
It generates all sorts of poisons in the air. It kills engines and components. It reduces fuel efficiency. Taxpayers send billions of dollars to the producers and pay additional billions for the product. It drives up the price of corn worldwide--a basic foodstuff--so others may starve.
But it gets votes.
