Best quality catalytic Converter & Oxygen Sensor Cleaner: MotorPower care Catalytic converter cleaner is a specially developed high-performance cleaner, preventive & cleaner for catalyst, turbocharger, and the EGR valve. Help to improve fuel efficiency, optimizes the engine performance. Product properties: For use in all Gasoline and Hybrid Engines. If the catalytic converter is lazy or clogged, we recommend our direct foam cleaner (DPF & catalytic Foam cleaner #8101). Use MotorPower Care catalytic converter cleaner regularly every 3-4 months or 3000 miles (which ever comes first). Instructions: Add Catalytic converter bottle to the fuel tank. Application Consumption: 250 ml mix with 7 to 12 gallons of gasoline. Mixing Ratio: 1:300 Reaction time: Works while the engine is running. Drive the vehicle for 40 minutes after adding it to the fuel tank, and every 10min, try to accelerate (floor it) the gas pedal while you are on open roads for a few seconds, repeat for a few times. Attention: We recommend inspecting the catalytic converter from the O2 sensor port for any cracks, by using an endoscope camera before using any cleaner. If catalytic converter is cracked, melted or broken then it's to late for any cleaner.
