For businesses with diesel vehicles, having a reliable source of diesel exhaust fluid (DEF) is critical since almost all diesel vehicles manufactured after 2010 require it. When DEF first became available, businesses would have to purchase DEF containers at the store or keep DEF in bulk tanks at their yards as many gas stations and truck stops did not provide DEF at the pump. Fortunately, as the demand for DEF increased, many gas stations and truck stops began supplying it at the pump for drivers.
Purchasing DEF at the pump is more convenient for drivers than carrying bulky containers in their vehicles, especially since they already have to stop at a station to purchase diesel fuel for their vehicles. It’s also typically more affordable than buying pre-packaged containers at retail stores.
The main challenge is identifying which fuel stations offer DEF at the pump. To help you find these locations, we created a state list and national map showing where you can buy DEF at the pump.
