SAY YES TO TESTED E-15

The National Corn Growers Association and its 40,000 members strongly support the EPA’s approval of E-15 for motor vehicles – a fuel blend that has been thoroughly tested.

 

The Research

 

In September 2010, the automotive engineering firm Ricardo found that moving from 10 percent ethanol in gasoline to 15 percent will mean little, if any, change in the performance of older cars and light trucks, those manufactured between 1994 and 2000. This study analyzed the vehicles manufactured by six companies and that represent 25 percent of light duty vehicles on the road today, concluded “that the adoption and use of E15 in the motor vehicle fleet from the studied model years should not adversely affect these vehicles or cause them to perform in a suboptimal manner when compared with their performance using the E10 blend that is currently available.”

In a February 2009 report, Oak Ridge National Laboratory for the U.S. Department of Energy performed a peer-reviewed study regarding the effects of E15 and E20 on motor vehicles and small non-road engines. This research concludes that when E15 and E20 were compared to traditional gasoline, there are no significant changes in vehicle tailpipe emissions, vehicle driveability, or small non-road engine emissions as ethanol content increased.

A major 2008 report was prepared by the State of Minnesota.

  • It compared the effects of E0, E10 and E20 on nineteen metals and found that the metals tested were compatible with all three fuels;
  • It compared the effects of E0, E10 and E20 on eight elastomers and found that E-20 caused no greater change in properties than E0 or E10;
  • It compared the effects of E0, E10 and E20 on eight plastics and found that there was no significant difference in the properties of the samples exposed to E20 and E10;
  • It compared the effects of E0, E10 and E20 on the performance of twenty-four fuel pumps and nine sending units and found that E20 has similar effect as E10 and E0 on fuel pumps and sending units;
  • And it tested forty pairs of vehicles on E0 and E20 and found no driveability or operational issues with either fuel.

An October 2008 report to the U.S. Senate on E20 ethanol research, prepared by the Rochester Institute of Technology, evaluated the effects of E20 on ten legacy vehicles. Initial results after 75,000 collective miles driven found no fuel-related failures or significant vehicle problems and documented reductions in regulated tailpipe emissions when using E20 compared to E0.

In October 2007, a report prepared by the Energy & Environmental Research Center and Minnesota Center for Automotive Research studied the effects of ethanol blends ranging from E-10 to E-85 on motor vehicles and found that exhaust emissions levels for all vehicles at all levels of ethanol blend were within the applicable Clean Air Act standards.

In December 2006, a report by the Coordinating Research Council evaluated the effects of E0, E6, E20 and E85 on the evaporative emissions rates from permeation in five newer California vehicles and found that there was no statistically significant increase in diurnal permeation rates between E6 and E20.

 

A 2004-05 research project by Stockholm University tested and compared evaporative emissions from E0, E5, E10, and E15 and found lower total hydrocarbon emissions and lower evaporative emissions from E15 than from E10 and E5.

A July 1999 study by the Minnesota Center for Automotive Research evaluated the effects of E10 and E30 in fifteen older vehicles in “real world” driving conditions. It found no effect on driveability or component compatibility from either fuel and found that regulated exhaust emissions from both fuels were well below federal standards.
