Study Finds Certain Ethanol Blends Can Provide Better Fuel Economy Than Gasoline
By Mr Ethanol | December 6, 2007
Earthtimes:
Research findings released today show that mid-range ethanol blends–fuel mixtures with more ethanol than E10 but less than E85–can in some cases provide better fuel economy than regular unleaded gasoline, even in standard, non-flex-fuel vehicles.
Previous assumptions held that ethanol’s lower energy content directly correlates with lower fuel economy for drivers. Those assumptions were found to be incorrect. Instead, the new research strongly suggests that there is an “optimal blend level” of ethanol and gasoline–most likely E20 or E30–at which cars will get better mileage than predicted based strictly on the fuel’s per-gallon Btu content. The new study, cosponsored by the U.S. Department of Energy and the American Coalition for Ethanol (ACE), also found that mid-range ethanol blends reduce harmful tailpipe emissions.
“Initial findings indicate that we as a nation haven’t begun to recognize the value of ethanol,” said Brian Jennings, executive vice president of the American Coalition for Ethanol. “This is a compelling argument for more research on the promise of higher ethanol blends in gasoline. There is strong evidence that the optimal ethanol-gasoline blend for standard, non-flex-fuel vehicles is greater than E10 and instead may be E20 or E30. We encourage the federal government to move swiftly to research the use of higher ethanol blends and make necessary approvals so that American motorists can have the cost-effective ethanol choices they deserve at the pump.” Full article.
