Does Engine Oil Burning Cause Significant Damage to the Catalytic Converter?

[StSpencer]

Engine oil burning causes significant damage to the catalytic converter. The burning oil adheres to the surface of the converter's honeycomb structure, reducing the effectiveness of catalytic materials such as palladium and rhodium, ultimately leading to converter failure. The direct consequence is failing vehicle emission tests. In severe cases, it can clog the converter, causing poor exhaust flow and reduced acceleration. Below are precautions for catalytic converter maintenance: 1. If the 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 after stable idling. 3. Check if the air-fuel mixture concentration is appropriate to ensure the liquid is atomized and drawn into the intake manifold. 4. Clean the catalytic converter only after cleaning the throttle body, fuel injectors, and combustion chamber. 5. During cleaning, avoid excessively high idle speeds to prevent overheating the catalytic converter.
