BlueDEF Diesel Exhaust Fluid is a non-toxic solution engineered to help diesel-powered vehicles reduce emissions and improve fuel economy.
Engineered for use in Selective Catalytic Reduction (SCR) systems on diesel engines, BlueDEF diesel exhaust fluid is comprised of a high-purity synthetic urea and deionized water mixture that improves emissions and fuel economy. Injected into the exhaust stream with a specialized dosing module, BlueDEF’s water vaporizes, leaving ammonia molecules en route to the catalytic converter; once there, it converts NOx molecules into harmless nitrogen and water vapor—making for cleaner emissions.
The BlueDEF Solution
BlueDEF® is a nontoxic solution of 67.5% purified water and 32.5% ultra pure automotive grade urea. BlueDEF® is not a fuel or fuel additive. Instead, when injected into the exhaust stream and passed over a catalyst, BlueDEF® helps convert NOx into nitrogen gas and water vapor — two harmless and natural components of the air we breathe.
