Flex fuel, also known as E-85, is a blend of 85% ethanol and 15% gasoline. It is designed for use in flex-fuel vehicles (FFVs) and offers several advantages over regular gasoline, including lower prices, reduced emissions, and support for American-made fuel. In Iowa, there are over 300 gas stations offering E85, and the Iowa Renewable Fuels Association is working to further increase its availability.

Flex fuel, also known as E-85, is a mixture of 85% ethanol and 15% gasoline
E-85 has been available for over 30 years and offers several advantages over gasoline. For example, it has a high octane rating of around 98, which reduces engine knocking. It also reduces emissions by more than 30% compared to regular gasoline. Additionally, E-85 is produced from renewable sources such as corn and sugar, making it a more environmentally friendly and sustainable option.
However, there are also some drawbacks to using flex fuel. Firstly, it is less economical than gasoline, which can make it more expensive to purchase. Secondly, ethanol absorbs dirt easily, which can potentially corrode and damage engines over time. Finally, ethanol contains less energy than gasoline, which can lead to lower gas mileage and reduced fuel economy.
In Iowa, the Iowa Renewable Fuels Association is working to increase the availability of E-85 across the state. Casey's Gas Station, which has locations across Iowa, sells E-85 and other ethanol-blend fuels.

E-85 has been available for 30 years and has an octane rating of roughly 98
E-85, also known as flex fuel, is a mixture of 85% ethanol and 15% gasoline. It has been on the market for 30 years and can be used in flex-fuel vehicles. E-85 has an octane rating of roughly 98 and reduces emissions by more than 30% compared to regular gasoline. It burns at a cooler temperature than regular gasoline and has increased resistance to detonation, allowing for more power without the cost of expensive race fuels.
Octane is a measure of a fuel's ability to resist knocking, which is the explosive or uncontrolled combustion of fuel in an engine's combustion chamber. Knocking can quickly destroy an engine, so higher octane fuel is required for high-performance engines. E-85's high octane rating makes it a popular choice for track cars and high-performance engines.
In North America, the AKI scale is used, which puts 98 octane fuel in the ~93 range. This is compared to California's 91 octane gasoline, which is the highest offered in the state. E-85 is also often compared to 91 octane fuel due to California's large tuning scene, which provides a lot of research data.
While E-85 can provide performance benefits, it may require upgrades to the fueling system to handle the alcohol and higher fuel consumption. Additionally, if the car is not already flex-fuel capable, E-85 can be rough on rubber fuel handling parts.
In Iowa, the Iowa Renewable Fuels Association is working to increase the availability of E-85 across the state. Casey's gas stations, which source their fuel from major petroleum suppliers, also sell E-85 at select locations across 16 states, including Iowa.

E-85 reduces emissions by more than 30% compared to regular gasoline
E-85, also known as flex fuel, is a mixture of 85% ethanol and 15% gasoline. It is approved for use in flex-fuel vehicles (FFVs) and can be found at gas stations across Iowa, among other states.
The production of E-85 also contributes to its reduced emissions. The carbon dioxide released by a vehicle when ethanol is burned is offset by the carbon dioxide captured when the feedstock crops are grown to produce ethanol. This is not the case with gasoline and diesel, which are refined from petroleum extracted from the earth. No emissions are offset when these petroleum products are burned.
Additionally, the use of E-85 can reduce greenhouse gas (GHG) emissions by up to 34% when corn-based ethanol is produced from dry mills. This reduction can increase to between 88% and 108% if cellulosic feedstocks are used. The American Coalition for Ethanol has also found that flex fuel reduces greenhouse gas emissions by at least 50% more than gasoline.
The adoption of E-85 can play a critical role in mitigating the impacts of climate change by reducing emissions and providing a cleaner alternative to regular gasoline.

Unleaded 88/E15 is EPA-approved for all 2001 and newer vehicles
Flex Fuel, also known as E-85, is a mixture of 85% ethanol and 15% gasoline that is approved for use in flex-fuel vehicles. It is a high-octane fuel that is commonly offered at gas stations in Iowa and other states. While E-85 is a popular option for flex-fuel vehicles, it is important to note that it should only be used when recommended by the vehicle owner's manual.
Unleaded 88/E15 is a type of fuel that is approved by the Environmental Protection Agency (EPA) for use in all 2001 and newer vehicles. This includes passenger cars, SUVs, and light-duty trucks. Unleaded 88 is a blend of 15% ethanol and 85% gasoline, which is slightly higher in ethanol content than the commonly used E10 blend. This blend provides several benefits, including greater cost savings, higher octane, and a similar fuel economy to E10. With Unleaded 88, drivers can expect to save between 10 to 30 cents per gallon.
The use of ethanol in Unleaded 88 offers a number of advantages. Ethanol is made from renewable sources, often corn, and is a cleaner-burning fuel that is better for the environment. It is also one of the least expensive sources of octane, which can help reduce fuel costs. Unleaded 88 is widely available at gas stations in Iowa, making it a convenient option for drivers.
It is worth noting that flex-fuel vehicles (FFVs) can utilize a range of ethanol blends, including blends with higher ethanol content than E15. FFVs can take advantage of the benefits of biofuel, such as E85, which contains up to 85% ethanol. E85 has been on the market for 30 years and offers reduced emissions, with an octane rating of approximately 98. Iowa has over 300 stations offering E85, making it easily accessible for drivers with compatible vehicles.
When choosing the right fuel for your vehicle, it is important to refer to the owner's manual for recommended fuel types. Additionally, considering factors such as fuel economy, emissions, and cost can help guide your decision. Unleaded 88/E15 is a reliable and cost-effective option for compatible vehicles in Iowa, offering the benefits of ethanol while being widely available at gas stations across the state.

E-10 is the most commonly sold fuel in the US and can be used by all vehicles
E10, also known as Unleaded, Super Unleaded, or Regular, is blended with 10% ethanol and 90% gasoline. It is the most commonly sold fuel in the US, accounting for over 95% of the fuel consumed in motor vehicles with gasoline engines. E10 is used in all vehicles on the road today, including motorcycles, boats, lawn mowers, and other small and off-road engines. It is also safe for high-performance vehicles.
E10 is beneficial for several reasons. Firstly, it burns cleaner than gasoline without ethanol, reducing engine knocking and protecting your vehicle in the winter as the ethanol acts as an antifreeze. It is also less expensive than gasoline without ethanol. Furthermore, ethanol-blended fuels are a pathway to compliance with the federal renewable fuel standard (RFS). The use of ethanol-blended fuels has been increasing since 2010, while the consumption of ethanol-free gasoline has been declining.
However, it is important to note that vehicle fuel economy may decrease by about 3% when using E10 compared to gasoline without ethanol. Nevertheless, E10 is still a popular choice due to its wide compatibility, environmental benefits, and cost-effectiveness.
While E10 is the most common blend, other blends such as E15 (15% ethanol) and E85 (up to 85% ethanol) are also available. E15 is EPA-approved for flex-fuel and light-duty vehicles with a model year of 2001 or newer, while E85 is approved only for flex-fuel vehicles. These blends offer higher ethanol content, but their sales remain limited due to various economic, environmental, and distribution challenges.
