Diesel Exhaust Fluid (DEF)

Diesel exhaust fluid must be used with modern diesel engines to reduce harmful emissions.  As those who operate fleets are well aware, trucks will simply stop operating if you run out of diesel exhaust fluid (DEF).  Furthermore, if DEF levels are allowed to run low, you may notice that your check engine light comes on, and eventually, the vehicle will simply stop operating, and you may void your warranty. And now, off-road equipment also contains selective catalytic reduction (SCR) technology, meaning that operators of off-road machinery must now buy diesel exhaust fluid as well.

Because of the importance of DEF as a prerequisite in keeping your trucks on the road and your off-road equipment in operation, so that they can make money for you, it is essential for you to have a reliable source of DEF supply and a reliable method for ensuring that your drivers or equipment operators are keeping the diesel exhaust fluid tank topped off.
