What is DEF?

Diesel exhaust fluid (DEF), the USA operating fluid for selective catalytic reduction (SCR), is a non-toxic solution that transforms harmful nitrogen oxide (NOx) emissions from America’s diesel-powered vehicles into harmless water vapor and nitrogen.

DEF reduces NOx emissions in the exhaust gas system of your SCR equipped diesel vehicle, be it a truck, a bus, a tractor, a car, a van or an off-road vehicle. PetroChoice offers not only the diesel exhaust fluid (DEF) product in itself but also a full range of related US diesel exhaust fluid storage and handling equipment to meet all North American fleet operators and individual requirements.

Diesel exhaust fluid and SCR, according to engine manufacturers, improves overall fuel economy by approximately 5% compared to competing technologies, and achieves NOx reductions in excess of 90%. New truck engine manufactures will comply with the emission standards imposed by the EPA Clean Air Act that came into effect on January 1st 2010. Under the new US regulations, most engine manufacturers have chosen the selective catalytic reduction (SCR) system as the most efficient way to meet these clean air standards.

Frequently Asked Questions About Diesel Exhaust Fluid:

How much DEF will my truck use?
Typically, one gallon of  DEF is used approximately every 300 miles.  A truck with a 20 gallon DEF tank can go up to 6,000 miles between fill-ups.

Will a truck quit if it runs out of DEF?
No.  An engine will not be shut down or be unable to restart as a result of running out of DEF.  However, if the DEF tank is empty, engine horsepower will de-rate and new DEF should be added to the tank.

Will DEF freeze in cold weather?
DEF begins freezing at 12 degrees Fahrenheit.  If DEF freezes, the engine will start and run properly (no de-rate or malfunctioning lights).  A DEF tank heater will thaw the fluid for use and at no point will this affect the operation of the engine.
