Cenex Renewable Fuels


CHS is one of the nation's largest suppliers of ethanol-enhanced gasoline. In fact, through their network of Cenex-branded retailers, they're the nation's largest retailer of E85 ethanol and other alternative fuel blends.

Ethanol is one of the most popular alternative fuels in the country today. Made from renewable, domestic resources such as corn, wheat or barley, ethanol is traditionally blended with petroleum fuel in a mixture of 10% ethanol and 90% gasoline called E10. E10 is aproved by almost every auto manufacturer in the world under their warranty programs. Higher concentrates, such as E85, 85% ethanol and 15% gasoline, are compatible only with flexible-fuel vehicles.

Ethanol-blended fuel has a higher octane and produces fewer harmful emissions than standard fuel. In fact, a blend with just 10% ethanol reduces emissions by up to 25%. In addition to the environmental benefits, using ethanol also helps expand the market for agricultural products and reduces our dependence on foreign oil. In fact, every 283 gallons of 10% ethanol-blended gasoline replaces one barrel of oil.

E-85 is available through select Cenex locations.


Biodiesel has been one of the fastest growing alternative fuels in the country. Most often made from the soybeans produced here in the United States, biodiesel provides superior engine protection from a renewable, domestic source.

Cenex has proudly introduced advances in biodiesel, such as Cenex Ruby Fieldmaster B2 premium soy biodiesel fuel -- an innovative biodiesel that delivers premium performance. Cenex Premium Biodiesels offer the same time and field tested benefits as their premium diesels, in a biodiesel blend. These biodiesel products are available through select Cenex Distributors.
