The recently approved use of E15 fuel made from blending gasoline and ethanol could damage vehicles and void warranties says the American Automobile Association (AAA), which is urging the federal government to ban it from the market.

The Environmental Protection Agency (EPA) approved the fuel earlier this summer, but AAA says only five percent of vehicles on the road are approved by the manufacturers to use the special blend they say causes significant problems such as accelerated engine wear and failure, fuel-system damage and false “check engine” warning lights.

The auto club conducted a recent survey it says identifies confusion among consumers as to which vehicles can use the fuel — 95 percent of those surveyed had never heard of E15, which contains 15 percent ethanol.

“It is clear that millions of Americans are unfamiliar with E15, which means there is a strong possibility that many motorists may improperly fill up using this gasoline and damage their vehicle,” said Robert Darbelnet, AAA president. “Bringing E15 to the market without adequate safeguards does not responsibly meet the needs of consumers.”
