Eurol DPF Cleaner is designed to enable the DPF to regenerate more easily when the diesel particulate filter has a higher-than-usual soot loading. During short trips, a diesel engine doesn’t get up to temperature and more soot is formed during combustion. DPFs clog up due to the quality of fuel, the engine oil quality or urban driving. DPF Cleaner uses a fuel-borne catalyst to lower the regeneration temp. from approx. 600°C to 400°C, allowing the carbon particles to be oxidized more easily.
