The best way to find the closest E85 fuel station is to use the U.S. Department of Energy Alternative Fuels Data Center at AFDC.Energy.gov or the search tool on E85Locator.net. Another option is to use the Flex-Fuel Station Locator app that works on Android phone systems, available at ChooseEthanol.com.
To use the Alternative Fuel Data Center, input your address, ZIP code or state in the search field to the left of the map. Clicking on the Go button leads to an interactive map of your area with the E85 stations pinpointed. The website lists the stations to the left of the map. Clicking on the individual buttons accesses operating hours, methods of payment accepted and what types of ethanol fuel are available at each station. E85 is just one type of ethanol-based fuel.
The E85Locator.net site has a station search tab in the left-hand column. Click on one of the states listed to bring up a list of stations in that state. The ChooseEthanol.net option allows you to scan the QR code to immediately download the app to your phone. It uses the same database as the U.S. Department of Energy's website. The app pinpoints your location and pulls up nearby stations.
