What is the reason why the new car burns engine oil

How much to burn? Try changing the oil;

The oil is not anti-wear;

Burning engine oil is blue smoke.

Hehe, I know that BMW cars burn engine oil because the oil is not anti-wear, some owners have used super American eutectic engine oil, burning 1 liter for 1,000 kilometers, and not dismantling the engine, which solves the problem of burning engine oil.

Most of the engine oil burned by Nissan Liwei is caused by the piston ring being trapped by carbon deposits. Relying on the addition of high-viscosity engine oil to continue life is only an expedient measure to cure the change. When the oil enters the combustion chamber to participate in the combustion, more carbon deposits will be formed, and the high base of carbon deposits will lead to the aggravation of the burning of engine oil, forming a vicious circle.

In the long run, it will cause cylinder wall strain, or even cylinder burst, and finally the engine can only be disassembled for overhaul.

Four reasons why you burn engine oil.

A ...If you don't clean the oil circuit for a long time or don't do effective oil circuit cleaning, you can use detergents at will, and using detergents and detergents with laughter effects are two different things;

IIThe antifreeze replacement cycle is too long or not changed at all;

IIIThe oil change interval is too long;

IVLong-term or often short-distance driving.

The above four points of the vehicle that burns engine oil must be occupied by one or all four points.

How the piston rings are stuck.

The principle of piston ring stagnation should start from the oil circuit, the oil bearing temperature is 110 degrees, and the high temperature caused by the long-term unclean oil circuit makes the oil at a temperature of 120 degrees or higher for a long time, so that the oil will be exhausted in advance, the small hole of the oil ring is very small, and the oil inside will be dried and scabbed for a long time. It becomes a liter of engine oil for 1000 kilometers or even hundreds of kilometers. Therefore, in order to solve the problem, we must start from the root oil circuit, which is the way to remove the root.

The solution to burning the oil.

In the habitual thinking of car enthusiasts, they always think that burning engine oil should be overhauled, so that they not only have to bear high maintenance costs, but also bear the unpredictable risks and depreciation losses brought about by the overhaul. Destroy the airtightness and precision of the engine. And there is a possibility that the engine oil will burn again after tens of thousands of kilometers, so overhauling the engine is not sustainable.

Now the no-dismantling technology has been very mature and gradually accepted by the majority of car owners. In particular, the non-destructive repair products containing PNF patented technology have completely gotten rid of the technical shackles of the operation of the auto repair shop, and the owner can operate it himself without removing a screw, and the piston ring is repaired and released during driving, and the effect is remarkable.

Landlord, the main reasons for engine oil burning are:

1.The oil seal of the air-trapped wheel door is aging and cracked.

2.The piston (oil) ring fails.

3.Cylinder walls, pistons and rings are worn, and the power decreases and abnormal noise.

4.The crankcase ventilation system is blocked.

First, the main reason for burning 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 the engine oil; In addition, poor sealing performance of the valve seal, damage to the crankcase forced draft valve (PCV) or crankcase vent blockage can cause excessive pressure in the crankcase to cause the oil to enter the cylinder with the crankcase gas and participate in combustion.

3. Burning engine oil caused by excessive oil filling. When the oil is filled above the center line, the part of the engine lubrication process that passes through splash lubrication will be too much into the combustion chamber due to the high oil pressure.

4. Oil leakage from turbocharger. The turbocharger is mounted at the front of the exhaust pipe and operates at a very high temperature, and the turbine and pump wheels can reach 120,000 revolutions per minute when the engine is running at full load. The turbine shaft has oil-lubricated floating bearings, and the car has one oil passage to the turbocharger.

Oil leaks from pipes or bearings can allow oil to seep from the turbocharger into the exhaust pipe. When the temperature of the exhaust pipe is high, the oil is baked and turned into blue smoke.

5. There is leakage in the valve oil seal, which means that the oil leaks into the combustion chamber through the valve oil seal.

Second, the method of preventing the burning of engine oil.

1. Use engine oil that meets the technical requirements of the vehicle. Many car owners never read the vehicle manual, and they don't know what quality and viscosity grade oil their vehicles use for a few years, and there is a lot of arbitrariness in the use of engine oil. When using engine oil, one is to pay attention to the quality index, and the other is to pay attention to the viscosity index.

The quality index refers to the grade above SL as much as possible, and the viscosity index should be strictly in accordance with the provisions of the viscosity index in the automobile manual, and cannot be too low or too high.

2. Avoid frequent rapid acceleration and long-term ultra-high-speed driving. When the engine rotates at ultra-high speed, it is easy to break the lubricating oil film, resulting in poor lubrication and dry grinding of the rotating part, and when it becomes a regular operation, it will make the engine wear abnormally and burn the oil, therefore, maintaining economic speed is one of the best ways to prevent the phenomenon of burning oil.

3. The oil must meet the specifications when filling. When the oil filling volume exceeds the center line, the repairman should be asked to pump out the excess oil, in addition, the oil volume should be observed before the next day.

4. If it is found that the engine oil is burned, the stool should be checked at the maintenance station as soon as possible. If it is due to engine failure (such as poor piston ring sealing, valve oil seal leakage, cylinder gasket leakage, etc.), you should go to the maintenance station as soon as possible to check and repair the fault as soon as possible.

Burning engine oil is caused by the oil is not anti-wear, and it is also a problem that cannot be solved by traditional engine oil. It seems that Want Want is a super American century lubricant, you can take a look.

What should I do if my car burns engine oil? What should I do if my car burns engine oil? My brother's less engine oil, do not burn the engine oil First test, whether to confirm the burning of engine oil, less engine oil does not mean that it is burned If you confirm the burning of engine oil, change the brand of engine oil, viscosity, Qingsun is good to wash carbon deposits, use repair agents, change oil seals to try to solve the problem Paoliwei here to ask this question, it is better to have a certified car owner and then black?

Burning engine oil basically has no repair, either change the car or change the car, or the socks will be driven with 40 engine oil Make sure the engine oil is less than half Hello landlord, this suggests that you drive the car directly to the after-sales side of the dealership to check and repair it, and see what the problem is Are you sure it is to burn engine oil? If yes, 1 then you can only do an inspection first, and then prepare for a major overhaul, even if it is repaired, you can only use 5w-40 engine oil in the future @2019
