A trade group representing Iowa's liquid renewable fuels industry says drivers in the state could save a lot of money if they switch to an ethanol-based fuel when buying gas.
The Iowa Renewable Fuels Association says drivers could have saved $69 million in 2012 if they switched to E15, a fuel blend containing 15 percent ethanol. They calculated the savings based on data from the state Department of Revenue.
The group says Iowans who drive 2001 and newer vehicles can use E15. They say E15 averages 5 cents per gallon lower than E10, a fuel blend with more gasoline.
