Top tips for keeping your Filter healthy

  • Use quality Fuel: A high quality fuel will create fewer particulates, and result in your Filter lasting longer.
  • Correct Engine Oil Grade: Using the correct Oil for your Engine is essential. Get in touch if you’re unsure about which Oil is right for your vehicle. Additional additives in some oils could cause issues.
  • Your Driving style: Slow driving, and stopping at the lights often is a sure-fire way to hasten the degradation of your DPF. Drive faster, and for longer periods without rest, and your Filter will thank you for it.
  • Passive regeneration techniques: Regular, consistent drives are the perfect way to keep your DPF in tip-top condition. The Soot in your Filter will clear (usually) given that you drive consistently for 30-50 minutes at a time, and at a speed of 40 MPH or higher.
  • Correct Vehicle Service intervals: A good rule of thumb is to have your Filter evaluated every 100,000 miles. We’ll also let you know whether your Filter requires attention when you bring it in for Servicing or Repairs.

The Facts

  • What is a DPF?: A DPF (Diesel Particulate Filter)  is a device designed to remove diesel particulate matter, or soot, from the exhaust gas of a diesel engine.
  • How it works: Diesel engines produce a variety of particles during combustion of the fuel/air mix due to incomplete combustion. Diesel particulate matter resulting from the incomplete combustion produces soot (black carbon) particles. Your Diesel Engine’s DPF catches a percentage of those black carbon particles. After a time, or with poor maintenance, your Filter will catch a lower percentage of the particles, and could become clogged by said particles.
  • Legality: Diesel Particulate Filters are a legal requirement for any vehicle running on diesel here in the UK. The removal of this Filter is punishable with legal action. Responsibly maintaining your Filter is the best course of action. If you believe that your Filter may not be working at full capacity, get in touch. Fines for drivers caught without a DPF can be up to £1,000 for cars, and £2,500 for vans. Removing your Filter could invalidate your insurance policy.
