How to judge whether the engine burns oil?

Identification method of combustion oil:

1, cooling the car and burning engine oil: Every morning when you get on the bus for the first time, a thick blue smoke will come out from the rear exhaust pipe. After a period of time, the blue smoke disappears, and there is generally no similar situation on that day.

2. Burning engine oil when accelerating: When the driver slams on the accelerator when the vehicle is running or when the vehicle is in place, the exhaust pipe emits a lot of blue smoke. Seriously, when the vehicle is driving, the driver slams on the accelerator and can see the blue smoke emitted by the reflector on the exhaust pipe side.

3. Fill up the "burning engine oil" vehicle with engine oil, and let the owner drive 1000 km, then go to the maintenance station to weigh the engine oil filter, and then fill up the engine oil, and then let the owner drive 1000 km. This is repeated three times to obtain the average value. After the running-in period, the normal oil consumption can generally reach 1000 km /0.3 liter. If it exceeds the standard, there is engine oil burning.

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 of piston-cylinder wall gap. All these are directly or indirectly related to the formation of carbon deposits. Considering the relationship between domestic oil products, it is necessary to use high-quality engine oil and (PNF) fuel additives, which is also the key to realize the problem of not disassembling or repairing engine oil.
