## Description

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.

Review: Works, but needs a day or two. - Took around 2-3 days but did get the check engine light off.
Review: Worked for me - So I poured the cleaner into my empty tank, then filled it up all the way with gas, so of course my check engine light is on with 3 codes about one of the o2 sensors having a slow response, so after I fill her up I went home, drove to work the next morning, 27 minute drive and the check engine light was still on, and my eco mode was not working, so on my way home from work, the check engine light was now gone and the eco was on for the ride home, so I will give 2 thumbs up for this product.

### ⭐⭐⭐⭐⭐ Works, but needs a day or two.
*by L***N on March 22, 2026*

### ⭐⭐⭐⭐⭐ Worked for me
*by V***L on October 8, 2024*

### ⭐⭐⭐⭐ It takes two.
*by K***N on October 23, 2024*

It works but, if the the converter is clogged bad, it’ll break up the particles and shoot it all over the O2 sensor. It may take more than one bottle but it works. Notable increase in performance….right before a jig saw. ☺️
