Reuters is reporting today that the Environmental Protection Agency is likely to delay a decision on the use of E15 in cars and pickup trucks built from 2001 to 2006 by up to a month.

Using an unidentified source, Reuter’s reporter Tom Doggett said the agency wants to do more testing on the effects of 15 percent ethanol blended gas and may announce today that the decision will be delayed. Last month, EPA made the decision that E15 was safe for use in cars and pickup trucks built in 2007 and later and that a decision on later model vehicles was expected by December.
