Casey's and Tennessee Corn Announce Expansion of E15 Fuel

Casey’s General Stores and the Tennessee Corn Promotion Board have announced the addition of E15 fuel at three Casey’s locations in northwest Tennessee, providing Tennessee drivers with a lower-priced, cleaner fuel option. Casey’s has committed to expanding its E15 fuel, known as Unleaded 88, to the Union City, Greenfield, and New Johnsonville Tennessee stations. The higher-octane fuel contains 15% ethanol and is approved for use in passenger cars, trucks, and SUVs with the model year of 2001 and newer. In fact, 9 out of 10 of the cars, trucks, and SUVs on the road today are approved by their manufacturer to run on E15. Together these vehicles consume 97% of the unleaded fuel sold in the United States.

The Tennessee Corn Promotion Board, through its Ethanol Expansion Program, is working with fuel retailers to expand the availability of E15 in Tennessee. Frequently sold as Unleaded 88, E15 is a blend of 15% ethanol and 85% gasoline. It contains 5% more ethanol than E10, which is the most common fuel used in the U.S. E15 is higher in octane — typically 88 octane while E10 has an octane rating of 87. Retailers are offering E15 as Unleaded 88 to highlight its high-octane value. 

“Casey’s is quickly embracing the value of expanding consumer choice by offering E15 fuel to its stations in Tennessee”, Tennessee Corn Promotion Board Chairman George McDonald said. “The Tennessee Corn Promotion Board incentive program for ethanol retailers is making this expansion possible. The goal of the program is to expand the availably of E15 fuel blends where they are typically not available,” said McDonald.  

There has been more testing of Unleaded 88 than any other fuel additive in the history of the EPA fuel waiver process. In 6 million miles of testing, the U.S. Department of Energy found no problems with the use of Unleaded 88 in the numerous vehicles selected.

“We are excited to offer our guests Unleaded 88 which is typically cheaper, better for the environment, and not yet widely available in this market. We hope to continue expanding our product offering in Tennessee, with this being our first major step,” said Casey’s VP of Fuels Nathaniel Doddridge. “E15 is a popular product in many of our other markets, and we look forward to the same success in Tennessee.”

“The Tennessee Corn Promotion Board actively promotes the use of ethanol fuels, and the corn checkoff provides incentives to help expand the availability of ethanol,” McDonald said.

Tennessee Corn plans to continue its work with fuel retailers to provide more access to E15 fuel at fuel stations across Tennessee.
