Ethanol has become commonplace in most gasoline blends in the United States to meet targets set by the Environmental Protection Agency (EPA) in 2007 for using renewable biofuels. The EPA has issued final targets for the amount of renewable fuel to be used in 2016 and that goal is 18.11 billion gallons, well short of the 22.25 billion intended target set in 2007.
To help meet this new goal the EPA is relying on expanded sales of E15 fuel and specialty E85 to increase renewable fuel consumption. While this may seem like a good plan, there are issues with running higher concentrations of ethanol-based fuels in vehicles not designed for it. Higher ethanol blends like E15 can cause metal corrosion, damage plastic and rubber components especially in vehicles produced before 2001.
SEMA is currently working with many other organizations from the automotive, boat, food and energy industries to repeal the EPAs E15 authorization and the mandate that requires 15 billion gallons of corn-based ethanol to be blended in the U. S. fuel supply every year.
