05 BMW 520 burn engine oil Is there any good solution for answering

The causes of BMW 520 engine oil burning and how to prevent it.

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 quality, driving conditions, driving habits, maintenance habits, etc., the following reasons will aggravate the oil consumption and cause the burning of engine oil, 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 weakens the oil scraping performance.

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.

Burning engine oil means that the engine oil enters the combustion chamber of the engine and participates in the combustion along with the mixture. The phenomenon of "burning engine oil" in the vehicle will damage the vehicle's oxygen sensor too quickly, resulting in an increase in carbon deposition in the combustion chamber, unstable idling, weak acceleration, increased fuel consumption, and excessive exhaust emissions.

Precautionary measures for burning engine oil:

1. Use high-quality engine oil

Engine oil is very easy to corrode and age in a long-term high temperature state, resulting in the oil film becoming thinner, and it is easier to escape to the combustion chamber to participate in combustion, so the use of high-quality engine oil can greatly delay this phenomenon.

2. Pay attention to the cleanliness of the fuel circuit

Fuel in the combustion process is indispensable to produce carbon deposits, and carbon deposits are the root cause of some car failures, such as the aging of valve seals, piston wall clearance, etc., all have a direct or indirect relationship with 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 to achieve, which is also the key to achieve no dismantling and repair to solve the problem of burning engine oil.

It is inevitable that the oil that plays a lubricating role between the piston and the cylinder wall in the engine will participate in the combustion, as long as it does not exceed one liter within 5,000 kilometers, it is normal oil consumption, and vice versa.

Burning engine oil is basically caused by piston ring stagnation. As long as there is no serious strain on the cylinder wall, it does not need to be overhauled. Changing the maintenance of high-viscosity engine oil is only an expedient measure to treat the symptoms rather than the root cause, and it will do more harm than good.

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 burning engine oil and having to go to the auto repair shop for overhaul, without removing a screw, repairing and releasing the piston ring stuck engine oil while driving, with remarkable results.

Solution The most fundamental way to solve the problem of burning engine oil is definitely to disassemble and repair and replace the worn parts, so that although the one-time investment is larger, the durability and reliability and the recovery of vehicle power are guaranteed.

Add 7 liters of engine oil to see the amount of oil in the display frequency Press the display frequency selection button You can see the vehicle data inside.

08 years of E60 523Li burning oil problem, you can go to the 4S shop to repair it for free, now it is not to replace the engine, but about this warranty is not limited to kilometers and years, 4S shop will be based on the actual oil consumption of your vehicle to see if you will be given a warranty.

In BMW, the main reason for burning engine oil is two aspects, one is the problem of accessories, waste gas valve, valve oil seal, cylinder pulling, and insufficient cylinder pressure. The second is that the oil circuit is not cleaned for a long time, the antifreeze is not replaced in time, the oil service life is too long, and the piston ring is stuck, and the more common situation is that the piston ring is stuck.

The reason why most of the car burns the engine oil is that the piston ring is stuck, the stagnation starts from the oil circuit, the oil withstand temperature at 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.

Burning engine oil is not incurable, there are two ways to solve it on the market, one is overhaul, and the second is PNF repair agent. In the case of overhaul, the cost is very high, the vehicle depreciates quickly, and the later run-in is also very troublesome. At the same time, I have also seen other riders use this repair agent, you can refer to it.

The reasons for burning engine oil in BMW and the quick solution to burning engine oil.

BMW's current N20 engine is actually burning oil, which is a normal oil consumption according to the official statement. Domestic consumers are too easy to fool, 1 general practice is to open the cylinder to replace the piston ring and valve oil seal, if the new car and the burn is not serious, it is not recommended to do this, 4S assembly engine process is too amateur relative to the factory, the seal is not good and there will be more, it is recommended to replace 1 of the fully synthetic engine oil, of course, you have to ensure the genuine product, run and see, if it is really the benefits of burning can only go to the claim.
