Recently the Federal Trade Commission (FTC) proposed a new rule regarding the labeling of ethanol blended fuels in order to “help fuel purchasers identify the correct fuel for their vehicles.” Ironically, the new rule would exempt any fuel meeting the Environmental Protection Agencies (EPA) E15 waiver from the proposed labeling requirements.
In the record section of the proposed rule, the EPA provides information under the “objections to the proposed labels” section openly stating that ethanol is harmful to motor vehicles, and specifically mentions that ethanol is damaging to motorcycles.
The EPA indicates two major ways that ethanol affects vehicles. First, ethanol enleans the air to fuel ratio by increasing the proportion of oxygen relative to hydrocarbons. This can lead to higher exhaust temperatures and can possibly cause catalyst failure by gradually deteriorating emission control equipment. Next, other component failures can occur due to materials compatibility issues with ethanol use.
The EPA also found, that ethanol can damage older conventional cars, heavy-duty engines, motorcycles, and non-road engines, explaining: “Older motor vehicles, heavy-duty gasoline engines and vehicles, motorcycles, and especially non-road products cannot fully compensate for the change in the stoichiometric air-to-fuel ratio as ethanol concentration increases. Over time, this enleanment caused by ethanol may lead to thermal degradation of the emissions control hardware and ultimately catalyst failure. Higher ethanol concentration will exacerbate the enleanment effect in these vehicles, engines, and equipment and therefore increase the potential of thermal degradation and risk of catalyst failure. In addition to enleanment, ethanol can cause materials compatibility issues, which may lead to other component failure and ultimately exhaust and/or evaporative emission increases… For older motor vehicles, heavy-duty gasoline engines and vehicles, motorcycles, and non-road products, the potential for materials compatibility issues increases with higher ethanol concentration.”
The Motorcycle Riders Foundation has been attempting to block the widespread sale of E15 and higher blends until they have been fully studied. The MRF supports U.S. House of Representatives bill H.R. 875, a bill that would halt the sale of E15 and commission an independent scientific study to determine all of the effects of E15 on an internal combustion motor.
The lack of demand for E15 has the EPA proposing that ethanol manufactures produce less ethanol than they have for the past few years.
Additionally a study done by the University of Nebraska, the third highest corn producing state in the country, found that using corn crop residue (considered a ready source for ethanol production) is harmful to the environment by generating more greenhouse gasses than traditional gasoline.
The Federal Trade Commission is still taking public comments on the labeling requirements. Simply slapping another label on a fuel pump is not the best way to prevent misfueling. Separate pumps, like diesel, need to be developed and installed. Let the FTC know that you don’t like the fact that fuels meeting the E15 EPA waiver are exempted, and more labels are not going to lead to less misfuels. The deadline is June 2nd and you can leave your polite public comments here: http://www.regulations.gov/#!submitComment;D=FTC-2014-0088-0001
More important than the labeling changes is the fact that the EPA is publicly admitting that ethanol is harmful to motorcycles, something the MRF has been stating for years. This revelation by the EPA is the sort of push we can use to rollback the sale of E15.

The Motorcycle Riders Foundation, incorporated in 1987, is a membership-based, national motorcyclists' rights organization headquartered in Washington, DC. The first motorcyclists' rights organization to establish a full-time presence in Washington, DC, the Motorcycle Riders Foundation is the only Washington voice devoted exclusively to the street rider. The MRF established MRFPAC in the early 1990s to advocate the election of candidates who would champion the cause of rider safety and rider freedom.The MRF proudly claims state motorcyclists' rights organizations and the very founders of the American riders' rights movement among its leading members. The MRF is involved in federal and state legislation and regulations, motorcycling safety education, training, and public awareness. The MRF provides members and state motorcyclists' rights organizations with direction and information, and sponsors annual regional and national educational seminars for motorcyclists rights activists, as well as publishing a bi-monthly newsletter, THE MRF REPORTS.
