PICKERINGTON, Ohio - The American Motorcyclist Association is asking the U.S. Environmental Protection Agency (EPA) to change a rule that will require all consumers to buy at least four gallons of gasoline from certain gas pumps after the new E15 ethanol-gasoline blend is introduced into the market.
The EPA revealed the requirement to the AMA in a letter dated Aug. 1, responding to the association's concerns that E15 -- a gasoline formulation that contains up to 15 percent ethanol by volume -- could be put in motorcycle and ATV gas tanks inadvertently when consumers use blender pumps. A blender pump dispenses different fuel blends through the same hose, and the vast majority of motorcycles and ATVs in use today are not designed to operate on E15 fuel, AMA stated.
The association has repeatedly expressed concerns to government officials and federal lawmakers about possible damage to motorcycle and ATV engines caused by the inadvertent use of E15 when the new fuel becomes widely available, and has asked that motorcycles and ATVs be part of any scientific study into the effects of E15.
"With E15 gasoline, our members who make a concerted effort to fuel their motorcycles or ATVs with E10-or-less gasoline may be unknowingly refueling with residual fuel left in the hose," Wayne Allard, AMA vice president for government relations, wrote in a June 20 letter to EPA Administrator Lisa Jackson. "Unlike an automobile or SUV that has a large fuel tank, the residual fuel left in a fueling hose could be detrimental to the performance of motorcycle or ATV engine due to the small size of their fuel tanks and the higher concentration of ethanol that would, therefore, be present in the fuel.
"In addition, the use of E15 will lower fuel efficiency and possibly cause premature engine failure," he wrote. "Use of E15 fuel voids many manufacturer warranties. In off-road engines, the effects can even be dangerous for users."
Byron Bunker of the EPA National Vehicle and Fuel Emissions Laboratory responded to the AMA on Jackson’s behalf.
"EPA requires that retail stations that own or operate blender pumps either dispense E15 from a dedicated hose and nozzle if able or, in the case of E15 and E10 being dispensed from the same hose, require that at least four gallons of fuel be purchased to prevent vehicles and engines with smaller fuel tanks from being exposed to gasoline-ethanol blended fuels containing greater than 10 volume percent ethanol," Bunker wrote.
"Additionally, EPA is requiring that retail stations that offer E10 and E15 from the same hose and nozzle use additional labeling to inform consumers about the minimum purchase requirement," Bunker wrote.
"Since motorcyclists and ATV users, as you suggest, have relatively small fuel tanks, they should pay careful attention to the labeling of blender pumps to ensure that an appropriate fuel is chosen, in this case E10 or E0," Bunker added.
