It isn’t clear what effect E15 will have on cars and in AAA president Robert Darbelnet’s mind, that’s enough to justify halting sales.

AutoGuide’s regular “Under the Hood” segment has already explained the vagaries of octane and the advantages of Top Tier gasoline, but there’s so much more to fuel than that. Ethanol, for instance, is a major component of gas, and something that’s a potential peril for consumers. But what is ethanol? And what is E85? Should you run these fuels in your vehicle?
The EPA will announce Friday that it has approved the use of E15 gasoline for vehicles made after the year 2000. The EPA previously approved the added ethanol content for vehicles made after 2007 – the new regulations would see the amount of vehicles able to use E15 grow exponentially, and directly benefit American corn farmers, whose crop is used in the production of ethanol.
The increased use of ethanol has been roundly criticized for its effect on food prices (more corn used for fuel causes the price of maize, a staple crop for much of the world, to rise), its environmental impact and the simple fact that most small engines are not designed for a such a concentration of ethanol.
Although ethanol is touted as a “green” fuel, the higher blends of ethanol in gasoline can have the effect burning out the catalytic converters, resulting in higher emissions.
