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?
