What should I do if I burn engine oil in an old car? Comprehensive analysis of causes and solutions
As the service life of the car increases, many old car owners will encounter the problem of "burning engine oil". Burning engine oil will not only increase the cost of using the vehicle, but may also cause damage to the engine. This article will combine popular topics and hot contents on the Internet for the past 10 days to analyze the reasons, impacts and solutions for old cars burning oil.
1. Common reasons for burning oil in old cars
Burning of engine oil is usually caused by wear or poor sealing of the internal parts of the engine. Here are a few common reasons:
| reason | Specific performance |
|---|---|
| Piston ring wear | Engine oil enters the combustion chamber, and blue smoke comes out of the exhaust pipe |
| Valve seal aging | Blue smoke comes out during cold start, and it will be lightened after hot car |
| Turbocharger failure | Supercharger leaks oil, oil consumption increases dramatically |
| Carbon accumulation inside the engine | The engine oil is adsorbed by carbon deposits, resulting in insufficient lubrication |
2. The impact of burning engine oil on vehicles
Burning engine oil will not only increase the cost of using the vehicle, but may also have the following impact on the engine:
1.Power drop: The engine oil enters the combustion chamber and reduces the combustion efficiency of the fuel, resulting in insufficient engine power.
2.Increased carbon deposits: Burning engine oil will accelerate the formation of carbon deposits and further affect the performance of the engine.
3.Exhaust exhaust: Burning engine oil will cause the exhaust gas to contain a large amount of harmful substances and may not pass the annual inspection.
4.Engine damage: Long-term burning of engine oil may cause insufficient engine lubrication, and in severe cases, it may even require overhaul.
3. Solution to the old car burning oil
For different reasons for burning engine oil, the following solutions can be adopted:
| Solution | Applicable | Estimated cost |
|---|---|---|
| Replace the piston ring | Severe wear of the piston ring | 2000-5000 yuan |
| Replace valve oil seal | Oil seal aging | 800-1500 yuan |
| Turbocharger repair | Supercharger leaks oil | 1500-4000 yuan |
| Carbon cleaning of engine | Carbon deposits cause oil burning | RMB 300-800 |
| Use high viscosity oil | Bring the engine oil slightly | RMB 200-500 |
4. Maintenance suggestions for preventing engine oil burning
In order to avoid the problem of burning oil in old cars, car owners can take the following precautions:
1.Regular oil change: Change the engine oil according to the maintenance cycle recommended by the manufacturer and avoid using inferior engine oil.
2.Pay attention to engine temperature: Avoid long-term high load driving and prevent the engine from overheating.
3.Use fuel additives: Regularly use cleaning fuel additives to reduce carbon deposits.
4.Check the turbocharger: Special attention should be paid to the maintenance of the supercharger for turbochargers.
5.Choose the right engine oil: Old cars can consider using slightly higher viscosity engine oil to reduce oil consumption.
5. Frequently Asked Questions for Car Owners
Q: Can the car burning oil still drive? A: You can continue to use it with a light burn of engine oil, but the amount of engine oil needs to be checked regularly. If the engine oil is burned severely (such as consumption exceeds 0.5 liters per 1,000 kilometers), it is recommended to repair it as soon as possible.
Q: Can using engine oil additives solve the problem of burning engine oil? A: For mild burning of engine oil, some repair additives may have certain effects, but they cannot cure the serious burning of engine oil.
Q: Is burning engine oil in an old car a precursor to scrapping? A: Not necessarily. As long as the oil burning problem is promptly repaired, most engine oil burning problems can be solved, and the vehicle can still be used for many years.
Conclusion:
Burning oil in old cars is a common but not to be ignored. By understanding the reasons, prompt repairs and preventive maintenance, the oil consumption can be effectively controlled and the service life of the car can be extended. If your car burns oil, it is recommended to go to a professional repair shop for inspection as soon as possible to avoid small problems and major failures.
