Why does Dongfeng Fengshen S30.3 million kilometers burn engine oil?

1. Use engine oil with poor quality or viscosity grade that does not meet the requirements. In addition, too low or too high oil viscosity can lead to poor engine lubrication, increased wear of piston rings and cylinder walls, and reduced sealing performance, resulting in oil burning.

2. The matching gap between the piston ring and the cylinder wall is too large, the piston ring is improperly installed or the sealing is poor, and the oil on the cylinder wall enters the combustion chamber, causing the phenomenon of burning oil.

Engine oil burning is due to the habit of not regularly cleaning the oil circuit and carbon deposits, resulting in the engine high temperature drying oil sludge and carbon deposits formed after fuel combustion stuck piston rings, as long as the cylinder wall and cylinder pressure are not problematic, the oil burning does not need to be overhauled. The related accessories that affect oil consumption, such as valve chamber cover waste valve assembly, valve seal, turbine, etc., can be directly replaced, as for the oil burning caused by piston ring stagnation, it is completely possible to use PNF patent and timely Siyoupu non-destructive repair agent to release and restore the elasticity of the piston ring during driving, and solve the problem of burning engine oil.

Hello, if you have run 300,000 kilometers, more than half of the valve seals are aging, and the piston ring clearance is large, and it is recommended to overhaul it.

If the oil burns severely, it is recommended to overhaul it, which is likely to be a large piston ring gap!

If there is a problem with burning oil, it is basically necessary to replace the piston ring and check whether it needs to be overhauled.

The engine oil itself has a certain amount of consumption, and excessive consumption is the problem of burning engine oil. There are many factors that affect the burning of engine oil, such as: fuel product trembling, driving conditions, driving habits, maintenance habits, etc., the above reasons will aggravate the oil consumption and cause the oil to burn, so that the vehicle appears

1. Carbon deposition occurs in the combustion chamber, which makes the gas ring of the piston ring stuck, and the sealing is poor.

2. Oil sludge is generated in the lubrication system, and the oil sludge blocks the oil return hole of the oil ring, and the oil scraping performance is weakened.

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

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

In addition, cars now have crankcase ventilation systems (exhaust valves), which can also exacerbate oil consumption if there is a problem. In the past, the problem of burning engine oil could only be solved by dismantling and repairing, but now there is a plan to solve the problem of burning engine oil without dismantling and repairing, which can be understood by taking a look.

Hello, it's a slight burn of oil, but it's not a big problem.

It depends on how you take care of it and what kind of oil you are changing

Dongfeng is a well-known brand in China, and it also strictly controls the quality, but it does not mean that the vehicle will not burn engine oil, how to solve and judge? If the vehicle is too old and the exhaust emits blue gas, it means that it is already very serious and the protective agent has no effect, and you must go to the 4S shop to replace it.

"Burning engine oil" will cause damage to the vehicle's oxygen sensor too quickly, resulting in an increase in carbon deposits in the combustion chamber, unstable idling, weak acceleration, rising fuel consumption, excessive exhaust emissions and other adverse consequences, resulting in insufficient engine lubrication, which will cause the engine to cause irreparable damage or even accident hazards in the long run, resulting in a significant increase in maintenance costs and even scrapping.

In the initial stage, YACCO lubricating oil pressure can be used for engine protection, which is used for the purpose.

It can reduce friction, extend engine life, and run the engine more smoothly.

Reduces fuel consumption and engine piston ring leakage.

Keep the oil seal and cushion soft.

Elimination"Cold start"problems, quickly restore horsepower.

Eliminates long-term accumulation of engine gels and oil film deposits.

Improve the cylinder compression ratio and inlet vacuum suction.

How to use: 1) Start the engine, idle it until it reaches normal temperature, and turn off the engine;

2) Drain the oil in the crankcase; (It is best to change the oil grid and filter it with new oil again to avoid the residue of old oil).

3) Add 2 litres of new oil to the crankcase;

4) Add 1 bottle of pressure engine protector to the crankcase; (Half a bottle can be added to the new car).

5) Continue to add some new engine oil to the crankcase (slightly less than 2 liters, pay attention to the oil dipstick scale);

6) Close the crankcase cover, close the engine cover, start the car, idle for 15 minutes or drive 20 km.

This is some of my practical experience, and at the same time, it can also solve the problem of burning engine oil, which is not necessarily the best, but it is actually used.
