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.

Hope answered ur question, Regards, ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good for Error Codes P0401 and P0420 *by on Reviewed in the United States October 3, 2026* Works well as described. Easy directions to follow. Just pour in the gas tank. I would recommend this product. Second time purchasing to keep system clean. ### ⭐⭐⭐⭐⭐ Worked on 1999 Toyota V6 that wouldn't pass smog. *by on Reviewed in the United States June 15, 2025* Bad coil on a 1999 V6 Toyota Solara coupe with 235,000 miles caused check engine light to come on (occasionally flashing) and engine to run rough for months. P0300 "multiple misfire" OBD code. Got progressively worse. Finally replaced the coil cuz a smog check was required for upcoming registration. Replacing the coil fixed the issue. Engine runs great. Check engine light was reset and did not come back, but smog check failed.Used this with 1/4 tank and drove til nearly empty to get rid of as much additive as possible, then added half a tank of top tier premium and drove for 1 hour.Passed smog by a wide margin.I can't confirm this product actually did anything, maybe the car just needed to be driven hard to clear out the carbon but you can't argue with the result!Oh yeah, recommended to a friend with a Kia mini van that wouldn't pass smog and also had a check engine light. Same procedure worked for him too. ### ⭐⭐⭐⭐ Not a cure-all *by on Reviewed in the United States June 4, 2026* It is hard to know how to review this product, except to say that it did not resolve my problems. My check engine light is still on with a P0420, and my catalytic converter is still not working. Did this product clean my converter? Maybe. My converter is not plugged up, but it really wasn't plugged up before. My converter apparently just doesn't have any precious metals any more. If you are looking at this product to fix a problem, chances are there is an issue further upstream that is causing the converter to underperform - dirty injectors, bad plugs, plugged EGR, or something else causing too much glop to go down the exhaust. Fix all that first, and then clean up the residue with this. ## Frequently Bought Together - Catalytic Converter Cleaner Pass Emissions Test Cleans Catalyst, Oxygen sensor and combustion chamber cleaner, fuel additive - Liqui Moly Catalytic System Clean 300 ml 7110.
