I’ve written in the past about how many drivers have reported significant drops in mileage when using a 10% ethanol-blended gas. That post spurred a ton of discussion, so I thought it would be worth highlighting a bit of ethanol-related news that I recently ran across…
Did you know that the EPA has approved E15 (gas with 15% ethanol) for use in 2007 model year and newer cars? In fact, they’re considering extending approval all the way back to the 2001 model year, depending on how their current round of testing turns out.
Apparently they took this action in response to a 2009 request by “ethanol backer” Growth Energy and 54 ethanol manufacturers. Keep in mind that this ruling simply allows E15, and does not require it. Still, this is something that you’ll probably run across at some point in the not-too-distant future.
In a subsequent article, USA Today tackled the question of exactly what this change means for you. In short, higher levels of ethanol could cause corrosion in engines not designed for it.
While proponents argue that ethanol is a great way to reduce our dependence on foreign oil, detractors have raised a number of concerns ranging from negative environmental effects to concerns over the impact of corn-based ethanol on food prices.
What do you think? Are you a fan of ethanol? Or would you prefer your gas straight?
