Trouble Maker
Since the introduction of DEF for our pickups, Ford, Dodge, and GM. Alot of people now believe that the DEF is used for the regen cycle of the DPF. No, it is not. The DEF is used to turn NOx into Nitrogen. The Particulate matter trapped in the DPF is still burnt out by the injection of Diesel from the engine.
DEF just allows the SCR/DPF to go much farther between regen cycles reducing the amount of diesel spent to clean the filter.
DEF will freeze below 12* F.
