Penrite P26 DPF Cleaner Aerosol 400mLPenrite P26 DPF Cleaner Aerosol is an easy to use, professional strength, workshop grade Diesel Particulate Filter (DPF) cleaner which effectively cleans and loosens carbon and ash deposits in a DPF. Its foaming formulation deeply penetrates the pores of the honeycomb structure of a DPF. P26 DPF Cleaner Aerosol is designed for use in all diesel engine vehicles fitted with a DPF in passenger cars, 4WDs, light and heavy duty commercial vehicles. Penrite P26 DPF Cleaner Aerosol is used to easily regenerate clogged or heavily soot contaminated DPFs and can be used as a solution or preventative measure. It should be used at the first sign of a blocked or heavily soot loaded DPF. This is usually identified by a warning light on the dashboard of the vehicle.When either a catalytic converter or a diesel particulate filter is blocked your vehicle may either go into limp mode or run a Check Engine light to advise of issues. This is where a quality catalytic or DPF cleaner pays for itself before these issues happen. By periodically running the required dosage through your fuel system, the exhaust emissions generated help break down this build up and ensure your exhaust is unobstructed and flowing freely.
