New England’s #1 Source For Diesel Exhaust Fluid

What is Diesel Exhaust Fluid?

What is Diesel Exhaust Fluid (DEF)? DEF is an aqueous urea solution used in Selective Catalytic Reduction (SCR) to reduce diesel exhaust emissions into nitrogen, water and carbon dioxide (CO2). DEF was designed to meet 2010 EPA emission requirements in North America and helps improve fuel economy. SCR systems cannot run without DEF. Therefore, SCR systems can be found on 2010-present model trucks, diesel pickups, and SUVs. Our Diesel Exhaust Fluid is available in Massachusetts, Rhode Island, Maine, Connecticut, New Hampshire, Vermont, and parts of New York
