DEF Search - Easily find diesel exhaust fluid (DEF) at the pump!

Hi Product Hunt 👋 I built DEF Search after running into a frustrating problem on the road: finding Diesel Exhaust Fluid (DEF) at the pump before it became urgent. If you drive a diesel truck, RV, or fleet vehicle, you know the alternative is often buying boxed DEF at a much higher price—or worse, scrambling when your DEF warning light comes on. DEF Search helps you quickly locate stations offering DEF at the pump across the U.S., so you can: ✅ Save money compared to boxed DEF ✅ Plan ahead on road trips ✅ Avoid unnecessary stops ✅ Find DEF faster when you actually need it I built this as an independent project for diesel drivers because I couldn’t find a simple, dedicated tool that solved this well. I’d love feedback from: * Truck drivers * RV travelers * Diesel pickup owners * Fleet operators What features would make this even more useful for you?
