BlueDEF Diesel Exhaust Fluid

An American Petroleum Institute (API) Certified Diesel Exhaust Fluid. Improve Fuel Economy By Up To Five Percent While Reducing Exhaust Emissions.


Diesel Exhaust Fluid (AdBlue®) System Flow Measurement.

Selective Catalytic Reduction (SCR) revolves around the use of a urea solution that is injected into diesel engine exhaust gas to virtually eliminate all NOx emissions. While a mixture of 32.5% high purity urea in deionized water has been set as the standard fluid, testing of the supply pumps and systems is accomplished with deionized water and a lubricating solution of as little as 15% glycol.  Unlike testing with DEF, the low percentage glycol-deionized water solution leaves no residue or crystallization that could cause premature system failures and provides just enough lubrication to allow the flow meter to turn at very low flow rates with nearly zero back pressure.


The blue DEF Purity Guarantee:

We test each batch of BlueDEF® before we put our name on it. The batch code found on the box is your assurance that the DEF within is pure and has been tested to meet or exceed the strictest OEM standards.

Diesel Exhaust Fluid (DEF) is one of the key elements of the Selective Catalytic Reduction (SCR) process used by Diesel Engine builders to meet EPA 2010 regulations. Diesel Exhaust Fluid is a nontoxic solution of 67.5% purified water and 32.5% ultra pure automotive grade urea. Diesel Exhaust Fluid is not a fuel or fuel additive. Instead, when injected into the exhaust stream and passed over a catalyst, Diesel Exhaust Fluid helps convert NOx into nitrogen gas and water vapor – two harmless and natural components of the air we breathe.
