Fuels we offer


E-10 gasoline is blended with 10% ethanol and provides significant advantages to consumers. Not only does E-10 burn cleaner, but it is less expensive than gasoline without ethanol.

Unleaded 88

Casey's is proud to offer Unleaded 88, a blend of 15% ethanol and 85% gasoline, at select stores across our 16 states. Also known as E-15, Unleaded 88 is an environmentally friendly fuel approved by the EPA for use in vehicles 2001 and newer.


Also known as flex fuel, E-85 is a mixture of 85% ethanol and 15% gasoline that is approved for use in flex-fuel vehicles. Casey's sells E-85 at a number of stores across our 16 states.

Ethanol-free gasoline

We are happy to provide our customers with ethanol-free fuel to use in their cars, motorcycles, boats, and other small engines. Our 87 ethanol-free and 91 ethanol-free options are safe to use in all engine types.

High Octane gasoline

Our 93 Octane gasoline is safe to use in all engine types and is the perfect choice for your high-performance vehicles. This product is the highest octane available on the market today and has been proven to reduce the likelihood of engine knocking.


Biodiesel is a renewable, clean-burning alternative to regular diesel and can be found at all diesel stores in Iowa, Illinois, and Minnesota – as well as various other stores across our footprint. With few to no modifications, biodiesel can be safely used in most diesel engines.

Winterized diesel

Casey's is committed to keeping your diesel engine running 365 days a year. We honor this commitment by treating our diesel from November 1 – March 31 by utilizing Winter Additives for proper winter compatibility for local conditions.
