Star Tron has worked well for me.

Are we stuck with Ethanol blended into gasoline forever?

Sample quote

“The ethanol program functions as a hidden food tax—the most regressive of all taxes,"
Mario Loyola, a senior fellow at the Competitive Enterprise Institute, wrote for The Atlantic last year.
"And the effects on poor Americans are magnified for poor countries that depend on imports of food."
Ethanol's government-mandated grasp on agriculture is best exemplified with a startling statistic: "In the United States, the cultivation of corn for ethanol now requires a staggering 38 million acres of land—an area larger than the state of Illinois. By comparison, the total area of cropland used to produce grains and vegetables that humans eat is only about twice that acreage," Loyola wrote.
