Officials mandate minimum gas buys at certain pumps
August 07, 2012
The U.S. Environmental Protection Agency 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 American Motorcyclist Association in a letter dated Aug. 1, responding to AMA 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 all-terrain vehicles in use today aren't designed to operate on E15 fuel.
"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 engines due to the small size of their fuel tanks and the higher concentration of ethanol that would, therefore, be present in the fuel," Allard wrote.
"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 behalf of Jackson.
"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," he wrote.
Another problem with the new EPA policy, Allard said, is that not all motorcycle and ATV gas tanks hold four or more gallons.
"Not only do we find it unacceptable for the EPA to mandate that everyone -- including our members -- buy minimum amounts of gas, but the EPA answer simply won't work because of the sizes of many motorcycle and ATV gas tanks and the fact that off-highway riders take containers of gas with them on their trips, and most times those containers are much smaller than four gallons," Allard said.
"The EPA needs to come up with a better solution," he said. "The EPA also needs to back an independent study to determine whether E15 is safe for motorcycle and ATV engines."
The AMA 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.
Ethanol is essentially grain alcohol produced from crops such as corn that is mixed with gasoline to produce an ethanol-gasoline blend motor fuel. In October 2010, the EPA approved the use of E15 in model year 2007 and newer light-duty vehicles (cars, light-duty trucks and medium-duty passenger vehicles). Then, in January 2011, the EPA added model year 2001-06 light-duty vehicles to the approved list.
No motorcycles or ATVs are currently on the list.
