When it comes to separating ethanol fact from fiction, few people are more qualified than Brian West.
A 31-year automotive engineer and former deputy director for fuels, engines, and emissions research at
Oak Ridge National Laboratory, West has spent decades testing ethanol blends in real-world vehicles. Recognized by the IL Corn Growers Association with its 2020 Ethanol Excellence Award, he joined IL Corn TV host Shane Gray to address common ethanol myths and explain why higher blends could play a larger role in America's fuel future.
Debunking the Oldest Myth in the Book
West said one of the most persistent myths is that ethanol takes more energy to produce than it delivers or doesn't reduce emissions and it's simply false.
Research from the Department of Energy,
USDA, and national laboratories has shown modern corn ethanol has up to 50%
lower carbon emissions than 100 % gasoline. As West puts it, today's ethanol is more than 47% sunshine, with much of its energy coming directly from the corn plant.
Why Octane Matters More Than Ever
Ethanol provides a high-octane fuel component at a cost often lower than gasoline. It boosts engine performance, helps lower refining costs, and can lead to savings at the pump. West also highlighted the potential of policies, which could encourage more efficient engines designed to take advantage of ethanol's octane benefits.
Is E15 Safe for Your Engine?
According to West, the science is settled. Through
Department of Energy research, he tested more than 100 vehicles on ethanol blends up to E30 and found no engine damage.
That research helped support EPA approval of
E15, which is considered
safe for vehicles model year 2001 and newer and is now approved by most automakers.
The Fuel Economy Question
While some older vehicles experienced a slight reduction in fuel economy with higher ethanol blends, newer vehicle testing showed E15 matching (or even slightly improving) fuel economy compared to E10. West believes future engines designed for higher-octane fuels like E25 and E30 could deliver both efficiency and performance benefits.
Infrastructure Isn't the Barrier You Might Think
West argues the infrastructure needed for higher ethanol blends is largely already in place. Most fuel dispensers manufactured since 2016 are compatible with blends up to E25, and the transportation network for ethanol already exists. Compared to building EV charging or hydrogen fueling networks, expanding ethanol availability is relatively straightforward.
The Bottom Line
For West, ethanol delivers a combination of lower emissions, affordable fuel, reduced petroleum dependence, and stronger rural economies. As a domestically produced fuel, he sees ethanol as a practical solution that benefits consumers, agriculture, and U.S. energy security.
