NASCAR has agreed to new partnership to publicize its use of fuel containing 15 percent ethanol.
Local ethanol advocates gathered in Wichita, as well other cities around the country, to mark the partnership. Wichita is home to several ethanol industry companies.
NASCAR has recently moved to enhance its environmental image.
It comes at a time when many others also will be using the new blend, called E15. The Environmental Protection Agency recently allowed the move from E10 to E15 for vehicles built in 2007 and after. It has delayed a decision to allow it for vehicles between 2001 and 2006.

NASCAR formed the partnership through a new organization, American Ethanol, created by ethanol advocacy group Growth Energy with the support of the National Corn Growers Association and other key U.S. farming and ethanol leaders.
