Olsen’s Fuel is happy to offer you bulk DEF. In todays day and age DEF is used in nearly every piece of equipment. Let us keep you going with our bulk def delivery system. We can deliver straight out to the farm when you need it. We also can order in DEF storage tanks if you are wanting to keep some on hand at the farm or shop. We also provide DEF in jugs at our stations and the OLSENS BP Station carries it at the pump as well. Let us know when delivering fuels, oil, or propane and we can throw on a case of DEF if you're needing some to keep you going and don't have the time to get to town.
