What is DEF and how should I use it?

DEF is a high purity solution of urea in water (32.5%).  It is used to chemically reduce NOx emissions from trucks and buses powered by diesel engines.  DEF is contained in a separate tank and sprayed into the exhaust gases.  Never fill the diesel fuel tank with DEF.

How much DEF will I need?

You will not need to replenish DEF every time you refill with diesel fuel.  The DEF consumption will be approximately 3% of your diesel fuel consumption (for every 100 gallons of diesel consumed you would need 3 gallons DEF).

Is DEF harmful?

DEF is neither harmful for humans nor animals.  DEF is not explosive.  It is non-toxic.  If you get it on your skin or clothes, rinse with plenty of water.
