A new study from the Rochester Institute of Technology (RIT) finds benefits to the gasoline blended with 20 percent ethanol (E20).

The study by RIT’s Center for Integrated Manufacturing Studies indicates that E20 reduces emissions of hydrocarbons and carbon monoxide compared with traditional gasoline or E10 blends. In addition, the research team found no measurable impact to vehicle drivability or maintenance in conventional internal combustion engines.

Using a 10-vehicle fleet owned and operated by Monroe County, N.Y., researchers fueled the vehicles – all with older gasoline engines not specifically designed to burn ethanol blends – over the accumulation of at least 100,000 miles per vehicle. Researchers found that the fleet showed an average reduction of 23 percent for carbon monoxide and a 13 percent reduction for hydrocarbon emissions, with no measurable stress on vehicle operation or mechanics.
