Diesel Exhaust Fluid Operator Tips
Diesel Exhaust Fluid (DEF) is non-toxic and is made up of purified water and urea. It is stable and colorless. DEF is similar to baking soda in its alkalinity (pH). It is not a fuel but is used to reduce the level of nitrogen oxides in the emissions to meet standards.
In the Selective Catalytic Reduction (SCR) system, DEF is injected into the exhaust. It converts the NOx into nitrogen gas and water vapor, harmless components of air.
Keep DEF out of direct sunlight. The ideal temperature range for storing DEF is 32° F to 86° F, and its average shelf life is 3 years. DEF begins freezing at 32° F. The DEF tank on the vehicle has a heater that will thaw the DEF quickly. Freezing and thawing does not change its effectiveness.
Because of its alkalinity, it can cause oxidization in the same way that oxygen rusts raw steel, so it needs to be stored in plastic or stainless steel containers.
