WASHINGTON — Nearly two-thirds of cars on the road could have more corn-based ethanol in their fuel tanks under an Environmental Protection Agency decision Friday.
The agency said that 15 percent ethanol blended with gasoline is safe for cars and light-duty trucks manufactured between 2001 and 2006, expanding an October decision that the higher blend is safe for cars built since 2007.The maximum gasoline blend has been 10 percent ethanol.
This decision was made despite repeated warnings from industry experts who have been pleading for more time to perform exhaustive testing. Were they being overly cautious? That’s a difficult argument to make, particularly since one delay in testing came from the fact that the higher ethanol blend fuel melting down the seals in pumps and storage tanks during testing.
