E85 is a fuel blend containing 85 percent ethanol and 15 percent gasoline. Ethanol is an alcohol-based fuel derived primarily from corn in the United States. This fuel type has grown in popularity over the past two decades as more vehicles became compatible with higher ethanol blends and as drivers explored alternatives to traditional petroleum-based gasoline.

According to the U.S. Department of Energy, there were approximately 4,200 public E85 fuel stations across the United States as of 2023. This represents steady growth from previous years, though E85 stations remain less common than traditional gasoline stations. The distribution varies significantly by region, with higher concentrations in the Midwest—particularly in corn-producing states like Iowa, Illinois, and Nebraska—where ethanol production and infrastructure are well-established.
Drivers choose E85 fuel for several reasons. The most common motivation is cost savings. E85 typically costs 20 to 40 percent less per gallon than regular unleaded gasoline, depending on market conditions and location. For example, in Iowa during 2023, E85 averaged $2.00 to $2.30 per gallon while regular gasoline averaged $3.00 to $3.40 per gallon. However, it's important to note that E85 vehicles achieve lower fuel economy—generally 15 to 30 percent less than comparable gasoline-only vehicles—because ethanol contains less energy per unit volume than gasoline.
Environmental considerations also drive E85 adoption. Ethanol is a renewable fuel produced from agricultural crops. Burning ethanol produces fewer greenhouse gas emissions than pure gasoline when calculated over the fuel's entire lifecycle, including production and transportation. Additionally, E85 burns cleaner in terms of certain tailpipe emissions, producing less carbon monoxide.
Practical takeaway: Before seeking E85 stations, verify that your vehicle can use this fuel. Check your owner's manual or look for a yellow gas cap or E85 label near the fuel door—these typically indicate flex-fuel capability. Vehicles manufactured since 2010 are more likely to support E85, but some older models do as well.
Not all vehicles can safely use E85 fuel. Only vehicles specifically designed as flex-fuel vehicles (FFVs) or ethanol-compatible engines should use E85. Using E85 in a non-compatible vehicle can damage the engine, fuel system, and emissions controls. The good news is that identifying whether your vehicle qualifies is straightforward and requires no special tools or expertise.

The easiest method to determine compatibility is checking the fuel door. On flex-fuel vehicles, the fuel door or fuel cap typically displays an "E85" label or shows both "E85" and "gasoline" as permitted fuels. Some vehicles have a yellow fuel cap instead of the standard silver or black cap. If you open your fuel door and see none of these indicators, your vehicle likely cannot use E85.
Your vehicle's documentation provides definitive information. The owner's manual explicitly states if your vehicle is flex-fuel capable. If you don't have a physical copy, most manufacturers provide digital versions on their websites. For example, Ford, General Motors, and Chrysler all clearly identify FFV status in their manuals. You can also check the vehicle's door jamb label—the sticker on the driver's side door frame that lists vehicle specifications—which often includes fuel type information.
The Vehicle Identification Number (VIN) can also reveal compatibility information. Several free online databases allow you to enter your VIN to check vehicle specifications, including fuel type compatibility. The National Renewable Energy Laboratory (NREL) maintains a database of flex-fuel vehicles dating back decades. Additionally, your vehicle's title or registration documents may specify fuel type.
Current vehicle statistics show that approximately 20 million flex-fuel vehicles are registered in the United States. Most were manufactured by General Motors, Ford, and Chrysler. Toyota and Honda also produce flex-fuel models, though in smaller numbers. Manufacturers continue adding E85-compatible models to their lineups, particularly among pickup trucks and full-size vehicles where demand is highest.
Practical takeaway: If you're unsure about your vehicle's compatibility, contact your vehicle manufacturer's customer service department with your VIN and model year. They can provide a definitive answer within minutes. Alternatively, visit your local dealership, where service representatives can quickly verify your vehicle's specifications without charge.
Several free online resources help drivers locate E85 fuel stations. These tools display station locations, hours of operation, current prices, and sometimes additional details like payment methods or amenities. Using these resources is straightforward and requires only a vehicle's location and internet access.

The U.S. Department of Energy operates an Alternative Fuels Data Center website that includes an interactive map of E85 stations nationwide. Drivers enter their address, city, or ZIP code, and the map displays nearby E85 stations with details including exact addresses, phone numbers, hours, and whether the station is publicly accessible. Some listings include pricing information updated by users or station operators. The Department of Energy's resource covers over 4,200 stations and is regularly updated as new stations open.
Google Maps provides another straightforward option. Searching "E85 fuel near me" in Google Maps returns nearby E85 stations with addresses, phone numbers, directions, and user reviews. The search results also display hours of operation and whether stations are currently open or closed. User reviews sometimes mention fuel quality, facility cleanliness, and customer service experiences. However, Google Maps data depends on stations correctly listing themselves, so smaller independent stations may occasionally be missing.
Dedicated fuel price-tracking apps like GasBuddy offer E85-specific searches. GasBuddy allows users to filter by fuel type and displays prices per gallon at participating stations. The app shows price trends over time and includes user comments about specific locations. Some stations report prices more frequently than others, so price information's accuracy varies.
Station-operator apps provide information for specific fuel brands. Love's Travel Stops, Pilot Flying J, and Murphy USA all operate E85-serving locations and offer apps showing station locations and amenities. These apps work best if you already know a particular chain's locations in your area.
E85 Prices, a specialized website, compiles E85 pricing data from user submissions and station reports. While less comprehensive than broader resources, it focuses specifically on E85 and includes detailed price history for many locations, helping drivers track price trends in their area.
Practical takeaway: Use multiple resources for most accurate results. Start with the Department of Energy's Alternative Fuels Data Center for comprehensive station information, then cross-reference with Google Maps for additional details and user reviews. If prices are important to your decision, check GasBuddy or E85 Prices for current cost comparisons.
E85 pricing fluctuates based on multiple factors including crude oil prices, ethanol production levels, and regional market conditions. Generally, E85 costs less per gallon than regular gasoline, but actual prices vary significantly by location and season. Understanding these variations helps drivers make informed decisions about using E85 long-term.

National pricing data shows that E85 typically ranges from 30 to 40 percent less expensive per gallon than gasoline, though this margin changes regularly. In 2023, national average E85 prices ranged from approximately $1.80 to $2.50 per gallon depending on the month and location, while gasoline averaged $2.80 to $3.60. However, because E85 vehicles typically achieve 15 to 30 percent lower fuel economy than gasoline vehicles, the actual cost per mile traveled may be closer than per-gallon prices suggest.
Regional availability varies dramatically. The Midwest contains approximately 60 percent of all E85 stations in the United States, reflecting the region's massive corn production and ethanol refining capacity. Iowa leads with over 500 public E85 stations. Illinois, Minnesota, Nebraska, and Missouri all have 200 or more E85 stations. These states benefit from established ethanol production infrastructure and state policies supporting renewable fuels.
Coastal regions and southeastern states have significantly fewer E85 stations. Some states have fewer than 10 public E85 locations. This disparity reflects lower ethanol production in these regions, less developed infrastructure, and
