Suitable for: Diesel engines with a standard built-in or retrofitted DPF. Not recommended for heavy-duty trucks with continuously regenerating traps. Always refer to your vehicle’s handbook. Do not ignore the DPF warning light, as continued driving may cause severe soot build-up.
Product Description
STP® Diesel Particulate Filter Cleaner is specially formulated to clean and regenerate diesel particulate filters by removing built-up soot and carbon. It's ideal for vehicles used in urban or stop/start driving conditions such as taxis, delivery vans, and short trip commuters.
All diesel cars manufactured after 2009 are fitted with a DPF to trap harmful soot particles before they exit the exhaust. This treatment helps to keep your DPF working efficiently and avoid costly repairs.
Add one 200ml bottle to a full tank of diesel (treats up to 55L) every 1,800 miles / 3,000km. If the DPF warning light is on, add the cleaner and drive on a motorway or dual carriageway for at least 20 minutes to assist with soot burnout.
For heavily blocked filters, repeated treatments may be required to fully restore filter performance.
