Carlube DPF Cleaner has been specially developed to clear and regenerate dirty Diesel Particulate Filters that may have become blocked over time. DPF Cleaner lowers the temperature at which soot particles can be burnt off, which aids regeneration and increases fuel efficiency.
Add entire contents (300ml) to a minimum of 30 litres of diesel fuel in the fuel tank.
Drive as normal then refuel. Use every 3000km for best results.
