E15 has been approved by the EPA for 2001 and newer light duty cars, trucks and SUVs, along with all flex-fuel vehicles (FFVs). There are many things to consider before offering E15, and we have the resources to guide you through this process. If you have not reviewed our E15 Retailer Handbook, that should be the place to start. This handbook provides the accurate guidance needed to bring E15 to the marketplace.
