The fight over upping the ethanol blend in America's gasoline continues with an entire series of salvos from the different camps. What's at stake is raising the amount of ethanol blended into the gasoline supply from a maximum of 10 percent today (making fuel known as E10) to either E12 or E15.

Now that we've covered the ethanol-related debate surrounding a move from E10 to E15 from almost every angle, it's time to move on to a discussion about E12. With the Environmental Protection Agency choosing to postpone its decision regarding E15 until further testing can be conducted, an interim move to E12 is now the suggested solution by farmers, ethanol blenders and proponents of renewable fuels.

Last month, the Environmental Protection Agency (EPA) announced that its decision to raise the ethanol blend from ten percent (E10) to 15 percent (E15) had been postponed pending further testing. Prior to announcing the postponement, the EPA received reports from automakers suggesting that E15 could be detrimental to modern engines. Rather than act in haste, the EPA determined that in-depth testing of current vehicles could more accurately determine the effects of running E15. While the EPA's re

The Environmental Protection Agency (EPA) sets rules about the amount of ethanol found in gasoline that flows from the nation's pump. The current standard for blending ethanol with gasoline stands at ten percent (E10). With farmers holding pitchforks in the air in anger because they want to put more corn into cars, the EPA agreed to consider raising the ethanol blend to 15 percent (E15), a move that would avoid hitting the blend wall. As Green Car Advisor reports, the time to decide whether or
