Nearly 80 percent of the cars on the road can use E15, a high-octane fuel which is usually priced lower than regular gasoline and emits fewer greenhouse gases. As such, it's no surprise that more and more stations are begining to offer E15. But if you are a retailer, you probably have plenty of questions on what is needed for you to be able to offer this great fuel. The Renewable Fuels Association (RFA) has a comprehensive handbook that will answer all your queries. Click on the link below to download a E15 Handbook.
