E85 Scout

E85 Scout finds E85 stations across the United States and shows you what the ethanol content at each one actually tested at, from fuel tests submitted by drivers. Fuel sold as "E85" isn't always 85% ethanol, and the pump label won't tell you what you're actually getting. E85 Scout does. Every station shows its most recent verified reading, how many tests it has, and how long ago the last one was. FIND STATIONS - More than 5,000 E85 stations on a map, centered on your location - Search by station name, address, city, state, or ZIP - Filter by minimum ethanol %, test freshness, blend (E15 to E85), or verified stations only - One tap to copy an address or open it in Apple Maps, Google Maps, or Waze - Save favorites and sort them by distance, ethanol %, or most recent test KNOW THE BLEND - Current ethanol % from community tests, with color-coded freshness - Multiple blends per station where offered (E15, E20, E30, E40, E50, E85) - Verified stations are marked, and so are private stations CONTRIBUTE - Submit an ethanol test: enter your reading and photograph the test. A vision model reads the photo and checks it against your number before the result is published; anything unclear goes to human review. - Quick Verify: at a station without a test kit? Confirm it's still there so the next driver doesn't waste a trip. - Report stations that are closed, private, or listed wrong, and submit stations we're missing. - My Contributions shows what happened to everything you sent in, and why. TOOLS - Ethanol % calculator: enter your tank size, current fuel level, and current blend, and it tells you how many gallons of E85 and of pump gas get you to your target blend, with an octane and stoichiometric (AFR) estimate. - Add your car (year, make, model, and whether it's tuned) to your profile. - Light and dark mode. ACCOUNT AND PRIVACY An account (email and password) is required. Every reading in E85 Scout is attributed to the account that submitted it and rate-limited per account; that is what keeps the data trustworthy. Your location is read on your device to center the map, show distances, and confirm you're within 200 m of a station for Quick Verify; your coordinates are not sent to our servers, though a Quick Verify or a test you submit records which station you were at. Test photos you submit are published as the evidence behind your reading and are sent to a third-party vision model for verification. You can delete your account and its data from inside the app at any time. Coverage is United States only. Station data starts from the national alternative-fuel station database (NREL) and is kept current by the community. Support: support@e85scout.com Privacy policy: https://e85scout.com/privacy
