The federal government's move to allow more ethanol in gasoline could improve the outlook for the ethanol industry.

EPA officials said earlier this week that a couple dozen companies will soon be allowed to offer a blend of gas that includes 15 percent ethanol. It's called E-15. The previous limit was at 10 percent.

The bump up has some people concerned about the effect that more ethanol could have on the engines of cars and trucks.

Cathy Wurzer talks with Bruce Jones, co-director of the Minnesota Center for Automotive Research at Minnesota State University in Mankato.
