Can Burning Engine Oil Damage the Catalytic Converter?

[LeBennett]

Burning engine oil can damage the catalytic converter, which serves as an external purification device installed in the vehicle's exhaust system. It converts harmful gases such as carbon monoxide, hydrocarbons, and nitrogen oxides emitted from the vehicle's exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. Maintenance tips for the catalytic converter: 1. Avoid using leaded gasoline; 2. Avoid prolonged idling; 3. Do not let the engine speed fluctuate rapidly; 4. Avoid excessively delayed ignition timing; 5. Do not test for spark by pulling out the high-voltage wire for extended periods; 6. When measuring cylinder compression, disconnect the fuel pump's central control connector; 7. If any cylinder is found to be malfunctioning, stop the vehicle promptly to inspect and rectify the issue; 8. Do not disassemble it arbitrarily—ensure any replacement matches the engine specifications.
