It is injected into the exhaust stream of diesel engines equipped with Selective Catalytic Reduction (SCR) systems to break down harmful nitrogen oxide (NOx) emissions into harmless nitrogen and water vapor. This 55‑gallon drum is ideal for fleet operators and high‑volume users. You replace DEF when the vehicle’s DEF tank runs low—typically indicated on the dash—because running out can trigger limp mode or prevent engine start.
