ncreasing the amount of renewable ethanol blended into gasoline from 10% to 20% 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 year-long research effort found that increasing ethanol blends from 10% (E10) to 20% (E20) in a gallon of gasoline provided an effective fuel across a range of tests focusing on drivability and materials compatibility.
The State of Minnesota conducted the study as part of the process to meet a state law that requires ethanol comprise 20% 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.
