Frequently Asked Questions.

  • Diesel Exhaust Fluid (DEF) is a clear, non-toxic, and colorless fluid made from purified urea and deionized water. It's used in diesel-powered vehicles equipped with Selective Catalytic Reduction (SCR) systems to reduce harmful emissions.

  • Def is used to break down harmful nitrogen oxide (NOx) emissions into harmless nitrogen and water vapor. This process helps diesel engines meet stringent emissions regulations, reducing air pollution and improving air quality.

  • DEF is injected into the exhaust stream before it enters the SCR catalyst. When the exhaust gases pass through the catalyst, the heat causes DEF to break down into ammonia (NH3), which reacts with NOx to form nitrogen (N2) and water (H2O)

  • DEF is typically stored in a dedicated tank on the vehicle. There's a separate filler neck for DEF, usually located near the diesel fuel filler. Make sure to use a DEF-compatible nozzle when refilling.

  • The consumption of DEF varies depending on factors such as the vehicle's engine size and usage. On average, DEF consumption is around 2-3% of diesel fuel consumption. Modern vehicles often have DEF level indicators to warn when it's time for a refill.

  • Running out of DEF can lead to reduced engine performance and eventually result in the vehicle not starting. It's important to keep DEF levels topped up to ensure proper emission control.

  • DEF is non-hazardous, but it should be stored and handled in clean containers to prevent contamination. It should also be kept out of direct sunlight, as exposure to high temperatures can degrade its quality. 

  • Yes, DEF can freeze at temperatures below 12F (-11C). However, it doesn't damage the fluid, and it will thaw without any issues when the temperature rises.
