EPA and the biofuels industry have said the fuel blend — which contains 15 percent ethanol, rather than the standard 10 percent — is safe for cars made in 2001 or later.
Biofuels groups contend API and its oil-and-gas allies are concerned about losing market share.
Currently, E15 is only available at a handful of gas stations across the country. But more of it is needed to meet the blending mandate’s accelerating targets, which calls for mixing 36 billion gallons of biofuel into traditional transportation fuel by 2022.
“Oil companies are desperate to prevent the use of higher blends of renewable fuels,” Tom Buis, chief executive with biofuel trade group Growth Energy, said in a Tuesday statement. “They have erected every regulatory and legal roadblock imaginable to prevent our nation from reducing our dependence on oil.”
