What Causes Engine Oil Burning in Small Cars?
2 Answers
The reasons for engine oil burning in small cars are: 1. Using unqualified engine oil; 2. Not changing the engine oil for a long time; 3. Starting with a cold engine and high throttle; 4. Operating with insufficient engine oil for extended periods; 5. Running under high-temperature conditions for prolonged durations; 6. Operating at overload and high speeds for extended periods; 7. Running in poor air quality conditions and failing to replace the air filter on time. The solutions for engine oil burning in small cars are: 1. Promptly replace the valve oil seal to ensure valve sealing; 2. Regularly clean carbon deposits on the piston rings or directly replace the car's piston rings; 3. Pay attention to driving habits in daily driving and avoid overly aggressive driving.
The main causes of engine oil burning in cars are usually related to internal component wear. If the piston rings age or become damaged, oil can leak into the cylinders through the gaps and burn along with the fuel, producing blue smoke. The same happens when the valve guide seals fail, allowing oil to seep in. Issues with the turbocharger's oil seals also frequently lead to oil burning, as they may not seal tightly during high-speed operation. Overall engine aging and rapid wear, especially in high-mileage vehicles, make oil burning more likely. Neglecting inspections can lead to a sharp increase in oil consumption, potentially causing the engine to overheat and fail, resulting in costly repairs. It is recommended to frequently check the oil dipstick and perform timely maintenance to prevent worsening conditions.
