PETROMARK® 10201 DPF DIESEL PARTICLE FILTER CLEANER SPRAY. Diesel engines emit much more harmful soot particles, compared to petrol and/or LPG engines. By using a particle filter, the emissions of harmful gases reduces, which is better for our environment! Driving short distances, congestion and city traffic causes that the particle filter slowly silts up, as a result the exhaust gases pass through the filter more difficult and power decreases sharply. Therefore it is important to clean the particle filter regularly. A highly effective method to prevent this problem and/or remedy is to clean the particle filter with Petromark® 10201 DPF Diesel Particle Filter Cleaner Spray. Through the application of this effective cleaner a large part of the accumulated soot particles burn, so that the exhaust gases can pass through the filter quickly again.
