5. What is DEF? DEF is not a fuel or fuel additive
Operating fluid for Selective Catalytic Reduction Technology
67.5% de-ionized water / 32.5% automatize grade urea
Converts NOx into nitrogen gas and water vapor

6. What is DEF? Highly susceptible to contamination
Any surface that comes in contact with DEF must be clean and dry
Any exposure to hydrocarbon fuels will contaminate the product
Only stainless steel or additive free plastics are allowed when handling DEF

7. What is DEF? Not flammable
Non-hazardous substance but cannot be dumped down a storm drain
Must be returned to the storage tank
Or returned to the supplier

8. What is DEF?
Diesel Exhaust Fluid freezes at an ambient temperature of 12˚F
DEF can be used after it thaws out after being frozen
Keep Diesel Exhaust Fluid out of direct sunlight

9. What is DEF?
Store below an ambient temperature of 86°F as Diesel Exhaust Fluid can start to decompose
Wear some protection if you are handling large quantities, with danger of spilling
If spilt on the ground, inside the vehicle, or on paintwork wash down with plenty of water
