Ethanol in Gasoline Bad for Power Equipment, Critics Say

"A push to add more ethanol to fuel has opened a barrel of worms."
But a push to add another 50% to the ethanol content of some automobile fuel has opened a barrel of worms. Automakers say they don't know how it will affect their cars; power-equipment and boat manufacturers are predicting calamitous mis-fueling; and gas station owners are looking at a slew of legal and logistical impediments.
The Environmental Protection Agency has approved a request from the ethanol industry to allow ethanol content in a gallon of gas to climb from 10 to 15%. The waiver to the Clean Air Act to permit so-called E15 fuel applies only to cars and light trucks made since model year 2007, but the Outdoor Power Equipment Institute and manufacturers argue that once gas stations sell it, consumers will mis-fuel their power equipment, with terrible results.
The availability of E15 could produce "a train wreck in the marketplace," said the institute's attorney, Bill Guerry.
Opponents of E15 are considering a concerted legal action to try to reverse the waiver. "We don't know the long-term effects of E15 on automobiles," said Gloria Bergquist of the Alliance of Automobile Manufacturers. "There's a sweep of studies underway now, and we had urged EPA to wait until next year when more of these studies would be concluded."
In approving the waiver Oct. 13, EPA Administrator Lisa P. Jackson said "thorough testing has shown that E15 does not harm emissions control equipment in newer cars and light trucks."
Cheaper components and higher running temperatures are taking their toll. But critics say a 15% ethanol blend would shorten engine life more and make equipment prone to fuel leaks and fire hazards.
