Who can elaborate on the reasons why cars burn engine oil and why they burn engine oil?

Engine oil itself is consumed to some extent, and excessive consumption is the problem of burning engine oil. There are many factors that affect engine oil combustion, such as fuel quality, road conditions, driving habits and maintenance habits. The following reasons will aggravate the oil consumption, cause the oil to burn and make the vehicle appear:

1, carbon deposit appears in the combustion chamber, which makes the piston ring gas ring stuck and causes poor sealing.

2. Sludge is produced in the lubrication system, which blocks the oil return hole and weakens the oil scraping performance.

3. Wear occurs between the piston and the cylinder wall.

4, valve seal corrosion aging sealing performance failure.

In addition, there is a crankcase ventilation system (waste gas valve) on the car now, and if there is a problem, it will also increase the oil consumption.

Precautionary measures for fuel:

1. Use high-quality engine oil:

The oil is easy to corrode and age at high temperature for a long time, which leads to the thinning of oil film and easy to escape to the combustion chamber to participate in combustion. Therefore, using high-quality engine oil can greatly delay this phenomenon.

2. Pay attention to the cleanliness of the fuel circuit:

Carbon deposition is inevitable in the combustion process of fuel, which is the root cause of some automobile faults, such as aging of valve oil seal and widening gap between piston and cylinder wall. These are directly or indirectly related to the formation of carbon deposits, so keeping the oil circuit clean is of great help to prevent engine oil from burning. Of course, this requires the help of high-quality fuel additives.

3, with the help of external force:

The cleanliness of fuel oil circuit and the anti-aging degree of engine oil basically determine whether the engine oil can prevent burning. Therefore, considering the relationship between domestic oil products, it needs the help of high-quality engine oil and (PNF) fuel additives, which is also the key to solve the problem that the engine oil cannot be disassembled or repaired.
