Casey's offers ethanol-free fuel for cars, motorcycles, boats, and small engines
Ethanol-free fuel is available at select Casey's locations, and customers can choose from 87 ethanol-free and 91 ethanol-free options, which are safe for all engine types. The 91 ethanol-free option is the highest octane available on the market and can reduce the likelihood of engine knocking.
While some states, like Minnesota, have laws requiring the use of ethanol in gasoline, Casey's still offers ethanol-free options for customers who need them for classic cars, small engines, ATVs, and boats. These ethanol-free options can provide benefits such as improved mileage and fewer engine problems, making them a popular choice for small engines and outdoor equipment.
Casey's also offers higher ethanol blends, including E15 and E85, at select stores across 16 states. E15 is a blend of 85% gasoline and 15% ethanol, while E85 contains 85% ethanol and 15% gasoline for flex-fuel vehicles. These blends offer advantages such as cleaner burning, higher octane, and better environmental performance.

E-10 gasoline is blended with 10% ethanol and burns cleaner
Casey's General Store offers a range of fuel options, including ethanol-free gasoline. Their 87 ethanol-free and 91 ethanol-free options are safe for all engine types, including cars, motorcycles, boats, and small engines. However, some customers have reported confusion over the availability of non-oxygenated or ethanol-free gas at certain Casey's stations.
E-10 gasoline, on the other hand, is blended with 10% ethanol. This blend is commonly used in the United States, with more than 95% of motor vehicles with gasoline engines consuming it. E-10 gasoline offers several advantages over ethanol-free gasoline. Firstly, it burns cleaner, reducing carbon monoxide (CO) emissions by 20-30% and decreasing emissions of greenhouse gases like CO2 by approximately 2%. This helps to improve air quality and reduce the environmental impact of vehicle emissions.
Additionally, E-10 gasoline is less expensive than gasoline without ethanol. Ethanol is one of the least expensive sources of octane, resulting in lower fuel prices for consumers. The use of ethanol also contributes to decreasing U.S. dependence on foreign oil. However, it is important to note that while E-10 gasoline offers these benefits, it may also cause increases in evaporative emissions and certain pollutants, depending on factors such as vehicle age and weather conditions.
Furthermore, E-10 gasoline is widely compatible with most vehicles. All gasoline engine vehicles can use E-10 without any modifications. This compatibility further contributes to its popularity and widespread use in the United States.
In summary, E-10 gasoline, blended with 10% ethanol, offers advantages such as cleaner burning, reduced emissions, lower cost, and wide compatibility. These factors make it a popular choice for gasoline engine vehicles in the United States. However, it is important to consider the potential trade-offs in terms of increased evaporative emissions and certain pollutants under specific conditions.

Unleaded 88 (E-15) is a blend of 15% ethanol and 85% gasoline
Casey's offers ethanol-free fuel options for cars, motorcycles, boats, and other small engines. Their 87 ethanol-free and 91 ethanol-free options are safe to use in all engine types. However, it is important to note that the availability of these ethanol-free options may vary across different Casey's stations.
Casey's also offers Unleaded 88, also known as E-15, at select stores across 16 states. Unleaded 88 is a blend of 15% ethanol and 85% gasoline. It is an environmentally friendly fuel option that has been approved by the Environmental Protection Agency (EPA) for use in vehicles from 2001 onwards. This blend offers higher octane, resulting in a cleaner and cooler burn for your engine. The increased ethanol content in Unleaded 88, compared to the commonly used E-10 blend, contributes to its higher octane rating of 88.
Unleaded 88 provides several benefits. Firstly, it improves engine health by reducing engine deposits, boosting horsepower, and enhancing engine efficiency. Secondly, it helps to reduce pollution by burning cleaner, thereby lowering greenhouse gas emissions. Lastly, it offers cost savings at the pump, often being less expensive than regular unleaded gasoline and lower ethanol blends.
While Unleaded 88 is suitable for most modern vehicles, it is important to consult your owner's manual for the recommended fuel type for your specific engine. Additionally, while Unleaded 88 has been extensively tested, some concerns have been raised about its potential impact on engines not designed to handle higher ethanol blends. As a result, it is only approved for use in vehicles manufactured in 2001 or later.

E85 is a flex fuel with 85% ethanol and 15% gasoline for flex-fuel vehicles
Casey's offers ethanol-free fuel options for cars, motorcycles, boats, and other small engines. Their 87 ethanol-free and 91 ethanol-free options are safe for all engine types. However, it is important to note that the availability of these ethanol-free options may vary across different Casey's stations.
Now, let's talk about E85. E85 is a type of flex fuel that primarily consists of 85% ethanol and 15% gasoline. It is designed specifically for flex-fuel vehicles (FFVs) and should not be used in traditional gasoline engines. E85 is an abbreviation that refers to the blend ratio of ethanol and gasoline or other hydrocarbons. The high ethanol content in E85 results in a higher octane rating than regular gasoline, typically rated at 87 octane. This higher octane rating allows E85 to be used in higher-compression engines, which often produce more power.
E85 is a popular choice in countries like Australia and Brazil, where the climate is generally warmer. In the United States, the adoption of E85 has been encouraged through government subsidies, particularly in corn-growing states in the Midwest. The actual ethanol content in E85 sold in the US can vary, ranging from 51% to 85% to accommodate for colder climates, as ethanol has lower heating value, making it challenging to start engines in cold weather.
E85 is a flexible-fuel option that offers several advantages. Firstly, it is a renewable and domestically produced alternative to pure gasoline. Secondly, E85 has a cooling property due to the nature of ethanol, which can enhance engine performance. Finally, E85 is more affordable than regular gasoline, costing around 60 cents less per gallon. However, it is important to note that vehicles using E85 may experience reduced mileage performance.

Some Casey's gas stations have ethanol-free pumps, but availability varies by location
Casey's Gas Station offers a range of fuel options, including E10, E15, E85, ethanol-free products, biodiesel, and winter diesel. While the company is committed to providing ethanol-free fuel options, the availability of these pumps varies by location.
Some Casey's gas stations do have ethanol-free pumps, as confirmed by customer reports and images shared online. These pumps are often labelled with a white decal stating "Ethanol Free". However, the availability of these pumps is not consistent across all Casey's locations. Some customers have reported that certain stations do not offer ethanol-free fuel, while others have multiple pumps designated for ethanol-free gas.
The price of ethanol-free gas at Casey's is typically higher, ranging from $3.25 to $4 per gallon, depending on the octane level. Despite the higher price, some customers prefer ethanol-free fuel for their small engines, boats, and other vehicles to avoid engine problems and improve mileage.
It's worth noting that the legality and regulations surrounding the use of ethanol-free gas vary by state. For example, in Minnesota, it is technically not legal to use non-ethanol gas unless it is for classic cars, small engines, ATVs, or boats. Casey's has introduced E15 and E85 blends in several states, including Illinois, Iowa, and Kansas, and continues to expand its fuel options to meet customer demands.
