E10, a renewable fuel made of 10 percent ethanol and 90 percent traditional gas, is so widely available that ethanol is blended in virtually every gallon of unleaded gasoline in the U.S.

Ensuring Fuel Quality and Good Marketing Practices with Ethanol Blends

Here you will find a detailed reference manual to assist you with the technical information regarding product quality and integrity of U.S. market denatured fuel ethanol (DFE) for E10, E15 and flex fuels for FFVs.

This presentation describes historical ethanol use and provides background information on ethanol blended fuels specifications, ASTM standards and information about ethanol as a fuel and fuel additive.

System Preparations and Post Blending Maintenance

Best practices for offering ethanol

Tanks, Filters, Water

This presentation focuses on the necessary steps for successful introduction of ethanol blended fuels to a new or existing fuel distribution system.  Before introducing ethanol into a new storage and transfer system or during the process of converting an existing system to handle ethanol or ethanol blended fuels, a thorough system evaluation should be conducted to ensure appropriate components and safety equipment have been selected and installed. This evaluation should include training of employees and personnel as well as review of safety and regulatory precautions. Just as with gasoline, there are many regulatory considerations that also must be investigated when offering ethanol blended fuels.

Phase Separation

Ethanol has infinite solubility with water, a major chemical difference from gasoline. With appropriate system overview and conversion procedures, water concerns can be completely mitigated. The following presentation contains information about proper procedures to prevent phase separation.

Transportation and Safety

Safety must be the number one goal when handling, transporting, and distributing transportation fuels, including ethanol. First responders and transportation personnel should be familiar and well prepared for ethanol emergencies. Important safety information can be found in this presentation.

Converting to Ethanol Blended Fuels?

The RFA has developed an extensive checklist to assist retail stations wanting to offer ethanol blended fuels. The key to a smooth and seamless transition is a thorough investigation and implementation plan. This checklist hopes to provide essential step by step information to help ensure a successful transition.

Fuel Economy

Determining the exact cause of reductions in fuel economy is not as easy as it seems. Fuel economy is the comparison of engine performance in distance terms with energy usage (miles per gallon), and it is influenced by many different factors, including excess cargo weight, vehicle condition and maintenance, proper tire inflation, use of air conditioning, consumer driving habits, climate related effects, and fuel composition. These factors produce similar and in most cases greater reductions in fuel economy than the use of 10% ethanol in gasoline. This document includes additional information on fuel economy.
