DPF and AdBlue Additives Available here. Do you know if your diesel vehicle requires DPF and AdBlue additives? Your vehicle’s DPF, or Diesel Particulate filter, traps soot in your exhaust and needs to be regularly emptied, or regenerated, by burning the dirt particles. DPF additives mix with your fuel to drop the necessary temperature for the dirt particles to ignite, a vital occurrence for vehicles with a DPF located farther away from the engine. AdBlue, a solution that reduces the amount of harmful emissions in diesel vehicles, is kept in a tank inside your engine. If your vehicle uses AdBlue and you run out, it might not start.
