Ethanol Blended Fuels have become increasingly popular as most auto makers are now producing “Flex Fluel” cars and trucks. This has led to higher supplies of ethanol in the United States making this fuel easier to find at a rapidly expanding number of locations.

Sonex Aircraft has begun its own scientific testing to optimize the AeroConversions AeroVee 2.0 for the use of ethanol-based fuels to take advantage of the lower emissions, affordable cost, and greater horsepower. As part of the testing, Sonex Aircraft has partnered with Renew Fuel Stations, an Oshkosh-based company that markets and distributes ethanol-blended vehicle fuel such as E85 - a blend of up to 85% ethanol with 15% gasoline. Renew currently operates 11 fueling stations across Wisconsin that feature renewable-based fuels for all gasoline engines and is an industry leader in the expanding retail market for these fuels.
