I maybe wrong in this, but I recently come upon this article from Ethanol Producer Magazine called "Big Oil’s Last- Ditch Effort" and its talking about the American Coalition for Ethanol and others have been cautioning about the E10 blend wall, the need for higher blends of ethanol, more blender pumps, and flex-fuel vehicles—putting consumers, not oil companies, in control, and doing so in a way that avoids any future blend wall problem. When federal law requires 36 billion gallons of renewable fuel to be used by 2022, much of that ethanol, they must overcome the blend wall. Here’s why oil companies are in panic mode today. While ethanol production will remain flat or decline this year, the RFS provides for annual increases in ethanol use, so refiners are expected to draw upon their stockpile of renewable identification number credits (RINs). As RIN stockpiles thin, refiners will need to purchase physical gallons of ethanol to comply with their renewable volume obligations under the RFS for the latter half of 2013 and into 2014. Moreover, at the same time the RFS ensures annual increases in renewable fuel use, new fuel economy standards are shrinking overall gasoline consumption in the U.S. When the RFS2 was enacted in 2007, we consumed around 150 billion gallons of motor fuel. Today that total is closer to 130 billion gallons. An RFS calling for ethanol use to rise from 13.8 billion gallons in 2013 to 14.5 billion gallons in 2014, while the overall gasoline pool is shrinking, means refiners can no longer refuse to comply with the RFS by dragging their feet to adopt E15.
And it’s E15 that’s got the oil lobby talking about the blend wall. The idea of farmers and ethanol producers taking more market share via E15 is giving Big Oil sleepless nights.
But all of this was real boring to me, but I guess from what I am learning about is the E15 has the ability to ruin our cars engine. The EPA will require that gas pumps with E15 bear a warning sign noting the blend and that it is not recommended for cars older than the 2001 model year. Automakers are also warning against using E15. BMW, Chrysler, Nissan, Toyota, and Volkswagen have all said that their warranties do not cover problems caused by using E15, and another eight companies have said using it may void warranty coverage, if they determine that's what caused the problem. It's not that filling up with E15 one time will screw up your engine, rather, the concern is that repeated, long-term exposure could cause the higher-alcohol-content fuel to degrade engine parts like valves and cylinder heads—which could potentially cost thousands of dollars to replace. Short-term, some may notice that their car isn't performing as well, and the "check engine" light might come on. And it could keep coming on, repeatedly, which is probably more annoying than dangerous. A few manufacturers have said they think that there needs to be a lot more study conducted to make sure there are no longer term effects on the vehicle, but so far everything they've seen says there will be.
Sorry this is so long, but its worth the knowledge and make sure you pay attention at the pump...
** The blending wall refers to the amount of ethanol gasoline companies are permitted to blend with petroleum-based fuel. Federal standards set the amount at 10% (E10) of gasoline consumption and maybe soon to be 15%(E15)
** RFS Renewable Fuel Standard
