Increasing the amount of renewable ethanol blended into gasoline from10 percent to 20 percent does not present problems for current vehicles or fuel dispensing equipment and provides similar power and performance, according to a new study released Wednesday by the State of Minnesota.
Using 40 pairs of vehicles commonly found on American roads, a yearlong research effort found that increasing ethanol blends from 10 percent (E10) to 20 percent (E20) in a gallon of gasoline provided an effective fuel across a range of tests focusing on drivability and materials compatibility.
"Using homegrown renewable fuel is an important part of Americanizing our energy future and unhooking our country from foreign sources of oil,” Governor Tim Pawlenty said. “This study shows that we can safely increase the amount of ethanol blended with gasoline for use in today’s vehicles. We’re proud that Minnesotais helping lead the nation to a cleaner, more secure energy future and we’re hopeful that other states will continue to join with us in this effort.”
The State of Minnesota conducted the study as part of the process to meet a state law that requires ethanol comprise 20 percent of all gasoline sold in the state beginning in 2013. Governor Pawlenty signed legislation that included this requirement in 2005. Minnesota and its partners will soon apply to the EPA for a waiver to federal rules that will allow E20 to be used in all of the state's gasoline.
