How it works
Three taps from
"where?" to "filled."
01
Search where you are
Drop in a city, ZIP, or highway exit. We map every bulk DEF dispenser nearby — not the jug shelf at the parts counter.
02
Check the status
See lane type, price per gallon, and whether it was confirmed working by a driver who just filled up. No more bagged-off pumps.
03
Skip the jugs
Bulk DEF at the pump runs 70–80% cheaper than boxed jugs. Fill up fresh and get back on the road.
Why bulk
The pump beats the box.
Every fill.
Jugs run $9–14 a gallon and leave you a stack of empties. Bulk DEF off the pump is roughly a third of the price, measured to the tenth, no funnel, no spill.
~$9 saved per 10-gal fill

Know a pump we're missing?
Every dispenser on the map was added by a driver. Confirm one you've used and the next RV, boat, or work truck rolls in knowing it's up.
