OpenFuel is a free, crowdsourced map of alternative-fuel stations across the United States. Find R99 renewable diesel, E85 flex fuel, and biodiesel (B5–B100) stations alongside regular gasoline (87, 89, 91, 93) and diesel #2, with up-to-date prices contributed by drivers.
Major fuel-finder apps treat alt fuels as an afterthought. OpenFuel treats R99, E85, and biodiesel as headline categories. Browse the map without an account; create one to confirm prices and submit photos of pump signs.
Station data is sourced from OpenStreetMap contributors and the U.S. DOE Alternative Fuels Data Center (AFDC), with deduplication and a 500-yard on-site geofence on every price submission.
