SEMA (Oct 14, 2010) - The U.S. Environmental Protection Agency confirmed that there is insufficient test data to permit E15 to be used in manufacture year 2000 and older light-duty motor vehicles. The SEMA Action Network (SAN) has consistently voiced concern that ethanol increases water formation which can then create formic acid and corrode metals, plastics and rubber. While the SAN is pleased with the decision that older cars should not be fueled with E15, the association is disappointed that the EPA issued an E15 waiver for 2007 and newer vehicles. The agency is still gathering data for the 2001-2006 vehicles. The EPA’s ruling responds to a request from the ethanol industry to raise the ethanol content in gasoline from 10 percent (E10) to 15 percent (E15).
Consumers will not see E15 at the pump any time soon. The EPA must first approve regulations on how gas stations will label their pumps to avoid consumer misfueling. This will take months. Furthermore, there is no obligation that gasoline retailers market the fuel. In fact, some retailers oppose the fuel over concern that they could be held liable if E15 damages a vehicle. The gas stations and distributors may also need to invest in new storage tanks, hoses and other equipment.
