What happened to Dongfeng Nissan, which burns engine oil with many models and talks about high quality?

The engine oil itself consumes a certain amount of energy. Excessive consumption will cause the problem of oil burning. There are many factors that affect oil burning, such as: fuel quality, driving road conditions, driving habits, maintenance habits, etc. The above reasons will increase oil consumption and cause oil burning, causing the vehicle to have the following:

1. Carbon deposits in the combustion chamber. , causing the gas ring of the piston ring to get stuck, resulting in poor sealing.

2. Oil sludge is produced in the lubrication system. The oil sludge blocks the oil return hole of the oil ring and weakens the oil scraping performance.

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

4. The valve seal is corroded, aged and the sealing performance fails.

In addition, cars now have crankcase ventilation systems (waste valves). If there is a problem, it will also increase the consumption of engine oil.
