What exactly is burning engine oil?
In fact, in the process of long-term driving, due to the friction of various parts of the engine, there are gaps inside the engine, which eventually leads to the oil seeping into the combustion chamber of the engine from the gaps, and participates in the combustion together with the mixture, thus forming the phenomenon of burning engine oil.
Burning engine oil will not only produce carbon deposits, unstable idling, but also increase fuel consumption and damage to the accelerated oxygen sensor.
Observe the exhaust gas: Observing the exhaust gas of the car is a simple way to determine whether the engine oil is burned. Normal exhaust fumes should be colorless or slightly light gray, while if the exhaust fumes appear blue or intensely black, this may be a sign of burning oil. Blue exhaust gas usually indicates that a large amount of unburned oil is entering the exhaust system, while a strong black exhaust gas may indicate a carbon deposit problem inside the engine.
Check the dipstick: Checking the dipstick regularly is a key step in determining whether the oil is burned. In the cold state, pull out the oil dipstick and check the level height of the oil. If the oil level is abnormally low, it may indicate that a large amount of oil is burning. At the same time, observe the color and cleanliness of the oil, if the oil becomes darker, cloudy, or has impurities, this may also be a sign of burning oil.
Pay attention to the sound of the engine:
Listening to the sound of the engine is also an easy way to tell. If the engine makes an unusual "hiss" or "rattle" sound at high rpm, this may be due to incomplete oil combustion.
Check the exhaust system:
Checking the carbon deposits in the exhaust system is also an effective way to determine whether the engine oil is burned. If there is too much carbon in the exhaust system, especially on the throttle and exhaust manifold, this may be due to burning oil.
There are many reasons for burning engine oil, such as the use of inferior engine oil, it is easy to form carbon deposits in the fuel injector, or the oil and oil filter are not replaced within the time limit, the cold car starts with a large throttle, and the operation is low oil for a long time, etc., which can easily cause the phenomenon of burning engine oil.
If you suspect that the vehicle has the problem of burning engine oil, you should add oil in time and send it to the repair shop for maintenance to protect the health of the engine and prolong the service life of the vehicle.
