E20: The Feasibility of 20 Percent Ethanol Blends by Volume as a Motor Fuel

Results of drivability and compatibility tests by the State of Minnesota have found that motor vehicles operating on a 20-percent blend of ethanol fuel will perform as well as those running on 10-percent ethanol or gasoline. The tests also found that using the higher E-20 ethanol blends did not cause significant problems for a wide range of materials, including metals, plastics, rubbers and fuel pumps used in vehicle fuel systems. The study used nationally recognized standards and protocols to ensure research quality. It was conducted at Minnesota State University Mankato and the University of Minnesota, with cooperation from the State of Minnesota, including the Minnesota Departments of Agriculture and the Pollution Control agency, and the Renewable Fuels Association. The study included input from fuel refiners, automakers and small-engine manufactures, and funding support from the Minnesota Corn Growers Association and the Council of Great Lakes Governors.
