Does Burning Oil Affect the Catalytic Converter?

[JuliannaLynn]

Burning oil does affect the catalytic converter. When an engine burns oil, it can adhere to the mesh surface of the catalytic converter, reducing the effectiveness of catalytic materials such as palladium and rhodium, ultimately causing the converter to fail. The direct consequence is failing vehicle emission tests. In severe cases, it can clog the converter, leading to poor exhaust flow and difficulty in accelerating. Precautions for using the catalytic converter: 1. If the catalytic converter has mechanical damage, thermal sintering, exceeds 200,000 kilometers in mileage, or suffers from lead poisoning, cleaning may not be effective. 2. If the engine stalls during cleaning, immediately disconnect the hose connecting the engine to the equipment and close the flow valve. Restart the engine and only reconnect and adjust after the idle speed stabilizes. 3. Users should check whether the air-fuel mixture concentration is appropriate to ensure the liquid is drawn into the intake tract in a mist form. 4. Users should clean the catalytic converter after cleaning the throttle body, fuel injectors, and combustion chamber. 5. During cleaning, the idle speed should not be too high to avoid overheating the catalytic converter.
