Burning engine oil in automobiles is a common problem in vehicle maintenance, which is usually manifested as an abnormal increase in engine fuel consumption and blue smoke from the exhaust pipe. Not only does this affect vehicle performance, but it can also lead to more serious engine damage. Therefore, it is necessary to discuss the causes and solutions of burning engine oil in automobiles.
Cause analysis
Burning engine oil in a car is usually caused by the following reasons:
Engine wear: Long-term use, improper maintenance, or the use of low-quality engine oil can cause wear and tear on internal engine parts (such as piston rings, cylinder liners, etc.), causing oil to enter the combustion chamber for combustion.
Seal Aging: Aging of engine valve seals and other seals can also cause oil to penetrate into the combustion chamber.
Oil quality: Using oil with improper viscosity can also lead to oil burning. For example, if you use an engine oil that is too thin, it will easily volatilize under high temperature and pressure.
PCV valve failure: Under normal circumstances, the PCV (positive pressure crankcase ventilation system) valve is able to vent the gas in the crankcase, if the PCV valve is blocked, the excessive pressure will cause the oil to be forced into the combustion chamber.
Solution
To solve the problem of burning engine oil in automobiles, different measures need to be taken according to different reasons:
Regular maintenance: Replace the oil and oil filter according to the manufacturer's recommended cycle, which can effectively prevent the occurrence of oil burning. At the same time, make sure to use high-quality oil that is suitable for the vehicle.
Replace worn parts: If you find that the engine is worn inside, you need to replace the worn parts in time, such as piston rings, cylinder liners, etc.
Replace the seals: In view of the problem of seal aging, the valve seal and other related seals should be replaced.
Check the PCV system: Regularly check whether the PCV valve and related channels are unblocked, and replace the PCV valve if necessary.
Use the right oil: Choose the right viscosity grade and make sure it's suitable for the current climate conditions and the use of your vehicle.
Precautionary measures
Prevention is always more cost-effective than solving the problem. Therefore, car owners should take the following precautions:
Follow a maintenance schedule: Maintain your engine in strict accordance with the manufacturer's maintenance schedule and avoid neglecting basic maintenance of your engine.
Use high-quality oil: Don't use low-quality oil to save money, a good oil can provide better lubrication and protection.
Gentle driving: Avoid long-term operation at high speeds and frequent hard acceleration and braking, which can reduce engine wear.
Check in time: Check the oil level regularly and keep an eye out for abnormal smoke from the exhaust pipe.
Watch out for squeak and noise: If there is an unusual sound in the engine, it should be checked immediately, as this may be a sign of wear and tear in the engine.
Conclusion
Burning oil in a car is not a minor problem that can be ignored, it can be a precursor to a more serious problem. Car owners can effectively solve and prevent the phenomenon of burning engine oil, keep the car in good condition, and prolong the service life of the engine. Once the phenomenon of burning engine oil occurs, it is necessary to diagnose and take corresponding measures in time, and ask professional technicians to check and repair if necessary to ensure driving safety and engine health.
