Product Data Sheet


What is Diesel Exhaust Fluid?

DEF is an aqueous urea solution used in Selective Catalytic Reduction (SCR) to breakdown diesel emissions into nitrogen, and water. DEF was designed to meet 2010 EPA emission requirements in North America and to also help improve fuel economy. SCR systems cannot run without diesel exhaust fluid. 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
