What's going on when the car burns oil
Recently, the issue of burning engine oil in vehicles has become one of the hot topics for car owners. Many car owners reported that the vehicle consumes too fast oil during use, and even causes engine failure. So, what exactly is the matter with burning engine oil in the car? This article will analyze this issue in detail for you based on the popular topics and hot contents of the entire network for the past 10 days.
1. What is burning engine oil?
Burning engine oil refers to the phenomenon that the engine oil enters the combustion chamber and is burned during the operation of the engine. Under normal circumstances, the engine oil consumption is very low, but if you find that the engine oil consumption increases significantly, blue smoke comes out of the exhaust pipe, or the oil warning light is on frequently, there may be a problem of burning the engine oil.
2. The main reasons for burning engine oil
According to popular discussions and technical analysis in the past 10 days, the main reasons for burning engine oil can be summarized into the following points:
| reason | Specific performance | Solution |
|---|---|---|
| Piston ring wear or damage | Engine oil enters the combustion chamber, and blue smoke comes out of the exhaust pipe | Replace the piston ring or overhaul the engine |
| Valve seal aging | Blue smoke comes out during cold start, and the oil consumes fast | Replace valve oil seal |
| Turbocharger failure | The turbocharger leaks oil, and the oil enters the intake duct | Repair or replace the turbocharger |
| Oil quality issues | The viscosity of the engine oil does not meet the standards, and the lubrication effect is poor | Replace the oil that meets the standards |
| Severe carbon deposits in the engine | Carbon deposits cause piston rings to stagnate and engine oil to swell | Clean the engine carbon deposits |
3. How to determine whether the vehicle burns oil?
There are mainly the following ways to judge the engine oil:
1.Observe the exhaust pipe: If the exhaust pipe emits blue smoke when it is started cold or accelerated, it means that the engine oil enters the combustion chamber and is burned.
2.Check the dip ruler: Check the dipstick regularly. If the oil consumption is too fast (such as more than 0.5 liters per 1,000 kilometers), there may be problems with burning the oil.
3.Spark plug inspection: Remove the spark plug. If there is obvious oil residue on the electrode, it means that the oil has entered the combustion chamber.
4.Using a Diagnostic: Read the engine data stream through the OBD diagnostic instrument to check for any abnormalities.
4. The dangers of burning engine oil
Burning engine oil will not only increase the cost of using the vehicle, but will also cause serious damage to the engine:
| harm | Specific impact |
|---|---|
| Engine power drops | Increased carbon deposits in the combustion chamber affect combustion efficiency |
| Exhaust emissions exceed standard | Combustion engine oil can produce harmful gases and pollute the environment |
| Shorten engine life | Inadequate lubrication leads to increased wear of parts |
| Catalytic converter damage | Materials produced by combustion of engine oil can clog the catalyst |
5. How to prevent and solve the problem of burning oil?
1.Regular maintenance: Strictly change the engine oil and filter according to the manufacturer's requirements and choose the appropriate engine oil viscosity.
2.Avoid long-term high-speed driving: Long-term high-load operation will aggravate engine wear.
3.Use fuel additives: Regularly use cleaning fuel additives to reduce carbon deposits.
4.Timely repair: Once the engine oil burning is discovered, you should go to a professional repair shop for inspection and repair in time.
6. Statistics on the problem of burning oil for popular models
According to the feedback and repair data of the car owner in the past 10 days, the problem of burning oil in the following models is more prominent:
| Car model | Frequently Asked Questions | High incidence period |
|---|---|---|
| A German brand A | Oil leakage of turbocharger, piston ring design defects | 2015-2018 |
| A Japanese brand B | Valve oil seal aging, motor oil consumption is too fast | 2010-2014 |
| A certain American brand C | Piston rings are stuck and carbon deposits are severe | 2012-2016 |
7. Summary
Burning engine oil is one of the common faults during vehicle use, but its reasons are complex and have great harm. Car owners should regularly check the oil condition, pay attention to abnormal vehicle performance, and take maintenance measures in a timely manner. Through scientific maintenance and correct driving habits, the occurrence of engine oil burning can be effectively prevented and reduced.
If you find that your vehicle has oil burning problems, it is recommended to go to a professional repair shop for inspection and repair as soon as possible to avoid causing greater losses.
