E85 is a blend of gasoline and ethanol. The name "E85" means the fuel contains 85% ethanol and 15% gasoline. Ethanol is an alcohol-based fuel made primarily from corn and other plants. This blend differs from regular gasoline, which typically contains only 10% ethanol or less.

People choose E85 for several reasons. Many drivers prefer it because ethanol is a renewable fuel source made from agricultural products rather than petroleum. Since ethanol comes from crops that can be replanted and regrown, some consider it more sustainable than traditional gasoline. Additionally, E85 often costs less per gallon than standard gasoline, which can reduce fuel expenses over time.
Another reason drivers select E85 is its performance characteristics. Ethanol has a higher octane rating than gasoline, which means it resists engine knocking better. Vehicles designed to run on E85, called flex-fuel vehicles or FFVs, can take advantage of this higher octane rating. Some drivers report improved engine performance when using E85 in compatible vehicles.
Environmental considerations also influence the E85 decision. Ethanol-blended fuels can produce fewer greenhouse gas emissions compared to pure petroleum-based gasoline during their lifecycle, from production through combustion. While ethanol production does require energy and resources, supporters argue the overall environmental impact is lower than traditional fuel sources.
Practical takeaway: Before using E85, check your vehicle's owner manual or look for a flex-fuel badge on your car. Only vehicles designed to run on E85 should use this fuel regularly, as using it in non-compatible engines can cause damage.
Not every vehicle can safely use E85 fuel. Using E85 in a non-compatible engine can damage fuel injectors, seals, and other engine components because ethanol is more corrosive than gasoline. Before searching for E85 stations, confirm your vehicle is flex-fuel compatible.

Several methods help you determine if your car runs on E85. The easiest approach is checking your vehicle's owner manual, which lists compatible fuel types. Look for terms like "flex-fuel," "FFV," or "E85-compatible" in the manual's fuel specifications section. This information typically appears in the fuel and refueling chapter.
Another way to check compatibility is examining the fuel door or filler cap inside your vehicle. Many flex-fuel vehicles have a yellow or green label on the fuel door indicating E85 capability. The label usually displays "E85" or "Ethanol" and describes the fuel types your vehicle accepts. Open your fuel door and look for this marking.
You can also inspect the vehicle's identification plate, sometimes called the door jamb sticker, found on the driver's side door frame. This label contains information about your specific vehicle's specifications, including fuel type. If your vehicle is flex-fuel compatible, it will be noted here.
An additional resource is the vehicle manufacturer's website or customer service line. You can provide your vehicle identification number (VIN) or registration information, and manufacturers can confirm whether your model year and trim level supports E85. Many automakers offer online tools that allow you to enter your VIN to view detailed specifications.
Practical takeaway: If you cannot find clear documentation confirming E85 compatibility, contact your vehicle's manufacturer or a certified mechanic before using E85. Using incompatible fuel can result in costly repairs.
Finding E85 stations near you has become simpler with online mapping tools and dedicated locator websites. These resources compile data about fuel stations across the country and their available fuel types. Learning to use these tools can save time and help you locate nearby stations.

The U.S. Department of Energy maintains a website called the "Alternative Fuels Data Center," which includes an interactive map showing E85 station locations. You can visit this government resource and enter your ZIP code or address to see stations in your area. The map displays station addresses, phone numbers, hours of operation, and sometimes user reviews. This data comes from stations that register with the database, though not every small station may be listed.
Google Maps is another practical tool for locating E85 stations. Open Google Maps on your computer or smartphone and search for "E85 near me" or "ethanol fuel stations near [your city]." Google pulls information from various sources and displays results with directions, hours, and sometimes photos. However, information accuracy can vary, so it's wise to call ahead before visiting a new station.
Fuel-specific apps like GasBuddy have added E85 station information to their platforms. These apps let you search for E85 in your area, compare prices at different stations, and read user comments about station conditions. Some apps send notifications when prices change, which helps you track fuel costs over time.
Individual fuel retailers and fuel networks also maintain their own station locators on their websites. If you prefer a specific brand or network, visiting their website directly often provides the most current information about their E85 availability. Many stations now update their inventory in real-time, so you can confirm E85 is in stock before making the trip.
Practical takeaway: Use multiple sources to verify E85 availability. A station may appear in one database but not another, or information may be outdated. Calling ahead takes only a minute and confirms the station has E85 in stock before you drive there.
E85 pricing fluctuates based on several factors, and availability varies significantly by region. Learning about pricing patterns and availability can help you make informed decisions about when and where to fuel up.

E85 prices typically depend on corn prices, crude oil prices, and seasonal demand. Since ethanol is produced from corn, when corn prices rise, E85 prices often increase as well. Crude oil prices also influence E85 cost because the fuel contains 15% gasoline. Additionally, seasonal changes affect pricing—winter blends and summer blends have different production costs, which may affect E85 prices throughout the year.
Geographically, E85 availability is not uniform across the United States. The Midwest, particularly states like Iowa, Illinois, Minnesota, and Nebraska, has the highest E85 station density. These states produce significant amounts of corn, making ethanol production and distribution more established. If you live in the Midwest, you'll likely find E85 stations relatively easily.
In other regions, E85 availability is more limited. Coastal states, mountainous areas, and less densely populated regions may have few or no E85 stations nearby. Some states are actively working to increase E85 infrastructure, but expansion takes time. If you live in an area with limited E85 availability, visiting the Alternative Fuels Data Center map can show you whether expansion is planned for your region.
Historical data shows that E85 prices are sometimes, though not always, lower than regular gasoline. However, because E85 contains less energy per gallon than gasoline, your vehicle's fuel economy will be lower when using E85. This means you may need to fill up more frequently. To determine whether E85 saves money in your situation, you should compare the price per gallon with your vehicle's fuel economy on E85 versus gasoline.
Practical takeaway: Track E85 prices in your area for a few weeks to understand your local pricing trends. Then calculate whether the per-mile fuel cost of E85 is actually cheaper than gasoline for your vehicle, accounting for lower fuel economy on E85.
If you've never used E85 before, understanding the fueling process can make your first experience straightforward. While E85 pumps operate similarly to regular gasoline pumps, some differences exist.

Most E85 stations have dedicated pumps clearly labeled for E85 fuel. These pumps are often grouped together and marked with green or yellow labels. Before approaching the pump, note its location so you position your vehicle correctly. Like all fuel pumps, E85 pumps require you to open your fuel door and remove your fuel cap.
At the pump, you'll typically need to swipe a payment card or pay inside the station before fueling. Some stations accept both payment methods. Enter your grade selection on the pump display—select "E85" rather than regular unleaded or premium gasoline.
