Diesel Exhaust Fluid (DEF)

DEF is federally mandated for all diesel vehicle models 2010 or newer. It is a solution made up of purified water and automotive-grade urea that is used as a carrying agent for the ammonia need to reduce nitrogen oxide (NOx) emissions from vehicles into nitrogen, water and carbon dioxide (CO2). As we move forward, Pioneer Oil would welcome the opportunity to assist our customers with questions on the product, as well as the delivery of DEF to your fleet.

Product quantities and packaged sizes range from totes of 330 gallon totes to 2 1/2 gallon cases with custom systems, pumps, hoses, and meters available for purchase. Please contact your sales representative or Pioneer Oil additional information on DEF.
