Does the public burn engine oil, does the public burn engine oil?

All cars burn oil, because the piston and cylinder wall must rely on oil lubrication, but some cars burn more, some cars burn less viscosity and grade can reduce the burning of oil, in addition to the number of car kilometers, inevitably the gap between the piston ring and the cylinder wall increases, the oil remaining on the cylinder wall increases, burn a little more, see some very old cars, a refueling hat blue smoke, is a typical burn oil normal maintenance, with the specified oil, the general family car, drive a 6-8 years, within 150,000 kilometers, One thing is for sure that the oil will not be consumed in large quantities, Volkswagen's cars generally consume a little more oil than Japanese cars, but it is not so exaggerated, first of all, most of the Volkswagen's engines use 40 viscosity oil, most of the Japanese cars use 30 viscosity oil, and the Japanese engine gears bite more closely, so it is necessary to use slightly thinner oil, and some car owners use 30 viscosity oil, which aggravates the consumption of engine oil. Polo This EA111 engine is suitable for SJ class and above.

40 viscosity engine oil, I saw that several car owners in the forum use 30 viscosity engine oil, and even 4S shops also use 30 viscosity engine oil, there are several 30 viscosity engine oils that do meet the standards of the public, there are certifications, but there are several values just up to the standard, close to the critical point, long-term use, will lead to the aggravation of oil burning.

It's not just Volkswagen that burns engine oil, but other models also burn engine oil, which is already a normal thing.

First of all, you have to confirm the reason for burning engine oil, the main reason for burning engine oil is two aspects, one is the problem of accessories, waste gas valve, valve oil seal, cylinder pulling, cylinder pressure is insufficient. 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.

Reasons for burning engine oil:

1.Do not do effective cleaning oil circuit for a long time, 2The antifreeze is not replaced in time, 3The oil life cycle is too long.

4.Long-term short-distance driving. The car that burns engine oil must occupy one or all four points. Please be seated.

Workaround:

Don't worry about burning engine oil, prescribe the right medicine, as long as the carbon deposition problem of the piston snap ring is solved, there is no need for overhaul, and the problem of burning engine oil can be directly repaired. Before burning engine oil, through many understandings, the vehicle was completely solved by using the method of dismantling and non-destructive repair of burning engine oil by Siyoupu.

The problem of adding one liter of engine oil for 1,000 kilometers, after fixing, there is no need to add oil for 5,000 kilometers. At the same time, it can clean the carbon deposits and colloidal impurities in the oil circuit, and the plugging of the fuel injector and the carbon deposits in the combustion chamber can be cleaned at one time.

As long as you use the general burning oil repair agent for 4 times in a row and drive more, you can clean the carbon deposits on the top of the piston and release the piston ring.

There are four common reasons for burning engine oil.

No, burning engine oil is not normal.

Burn the oil"This is when the oil enters the combustion chamber of the engine and participates in the combustion along with the gas mixture. Vehicles appear"Burn the oil"The phenomenon will cause the vehicle oxygen sensor to be damaged too quickly, resulting in an increase in carbon deposition in the combustion chamber, unstable idling, weak acceleration, rising fuel consumption, excessive exhaust emissions and other adverse consequences.

No, my car is also a Volkswagen, and I haven't noticed the burning of engine oil for more than nine years. Any new engine of the car will not burn the engine oil when it leaves the factory, and only if it is used improperly after driving and the maintenance is not timely, it will cause the failure of the oil burning.

Online information should pay attention to the screening of Volkswagen car sales are very high, if there is a serious quality problem, it must be. It won't go on for a long time, so to speak. Volkswagen cars rarely burn engine oil.

Why does Volkswagen burn engine oil.

In order to protect the engine and prolong the engine life, Volkswagen is designed to reduce the frictional resistance between the piston ring and the cylinder wall, and an oil film will be formed on the cylinder wall, and part of the oil film will be burned off with the gas burned at high temperature, so the oil loss is more than the same period last year.

1. Volkswagen's processing technology for engine cylinders, the engine cylinder wall is shown as a mesh shape under the microscope, each small mesh is a "small oil depot" for storing oil, and the piston has better lubrication performance than the flat cylinder wall when running up and down in the cylinder, which also minimizes the wear between the piston ring and the cylinder wall.

2. The toughness of the piston ring of Volkswagen is better, and the degree of tension is weaker than that of Japanese cars, simply put, it is strong, but the elasticity is small, and this matching naturally reduces the wear caused by the piston ring running up and down on the cylinder wall, so Volkswagen has driven hundreds of thousands of kilometers to measure the wear of the cylinder wall of its engine of the rolling machine, which is much smaller than other car series, and the engine can still maintain good working condition.

3. The engine is like the heart of the car, in the final analysis, the engine burns oil or the piston ring has a problem, under normal circumstances, there will be oil loss every 1000km, if it exceeds too much, it is possible to burn oil. If there is a problem with the sealing of the piston ring, the oil will follow the movement of the piston and secretly drill into the combustion chamber to participate in the combustion, and then the oil will be burned.

4. In order to prolong the service life of the engine, Volkswagen manufacturers cause engine oil to be burned.

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 thinning of the oil film, which is easier to enter 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 cylinder wall clearance, etc., all of which are directly or indirectly related to the formation of carbon deposits, so keeping the fuel circuit clean is of great help to prevent burning engine oil, of course, this needs to be done with the help of high-quality PNF fuel additives.

Volkswagen burns engine oil 1The reason for Volkswagen's oil burning: the oil separator often fails, resulting in the failure of oil-water separation.

And because the plastic strength of the end cover is not enough, the seal between the camshaft end cover and the cylinder block is not tight, resulting in oil leakage. There is also a design flaw in the pressure valve under the separator, which leads to oil leakage. Turbocharged cars require oil for cooling, so the oil will evaporate when the turbocharger is cooled.

2.In the process of guessing driving, driving habits and fuel quality can also cause the engine to burn oil. If acceleration too fast will lead to insufficient fuel combustion in the engine and carbon build-up in the engine, then poor fuel quality will also lead to carbon build-up in the engine after combustion.

So there are many factors that burn engine oil. So some car owners will burn engine oil, and some car owners will not burn engine oil. Now that Volkswagen has launched its third-generation engine, the oil burn situation has also improved.

The main reason for burning engine oil1. There is a problem with the accessories, the waste valve, the valve seal, the cylinder is pulled in the cylinder, and the cylinder pressure is insufficient.

2. The oil circuit is not cleaned for a long time, the antifreeze is not replaced in time, the oil service cycle is too long, the piston ring is stuck, and the more common situation is that the piston ring is stuck.

Solutions for burning engine oilOverhaul

First, overhaul, maintenance of multi-person operation technology is not unified and assembly is not good, the hot and cold value of the engine assembled at room temperature is not enough, overhaul 1-40,000, vehicle depreciation 3-60,000. The disadvantages of overhaul: do not turn on the engine as a last resort, after opening, there are traces of disassembly, the value of the ant beam car instantly depreciated a lot, and the result of the assembly is unknown.

In the process of dismantling and assembly, the humidity of the air, constant temperature, and low temperature are all unable to meet the operation of the dust-free workshop. Don't disassemble the engine without serious cylinder pulling. After the overhaul, 2000 kilometers to change a fully synthetic engine oil for two consecutive times, plus to find a good road condition to run in separately, 3000-5000 kilometers to complete the run-in, the cost of oil + gasoline is very high, and the cost of overhaul and run-in of ordinary cars is 2000 yuan.

And once you call the police, you can call a tow truck immediately, which is more troublesome.

Non-destructive repairThe second is that this kind of car burning engine oil is very easy to do, first check the exhaust valve to see if there is a problem, and then see if the cylinder wall wear is serious, there is no problem, it must be caused by the piston ring stagnation, because there is no cylinder wall wear is not required to overhaul. It has nothing to do with the valve seal, this car will not be broken for 16w km or 20w km. The problem of burning oil caused by piston ring stagnation is a phenomenon that occurs in most oil-burning vehicles, you can take a look at this Magotan owner method, he uses PNF repair agent, you can clean the carbon deposits on the top of the piston and release the piston ring.

How to know if the burning of engine oil is serious or not.

Decrypt the correct inspection methods and repair plans for burning engine oil.

Reasons why Volkswagen cars burn engine oil:

Valve oil seals. The valve is actually used to prevent oil leakage into the combustion chamber, but over time, it will more or less wear or age. If it is serious, it will affect the tightness of the valve, so it is easy to burn the engine oil.

The piston clearance is too large.

When the car is used for a long time, there must be carbon deposits attached to the piston ring, but if it is not cleaned for a long time, it is likely to expand the gap between the piston ring and the cylinder block, resulting in the oil flowing into the combustion chamber, resulting in the burning of engine oil, and in serious cases, it will also lead to the phenomenon of engine "bursting".

Driving habits. If we often accelerate sharply and drive at high speed for a long time (high-speed operation of the engine), it is easy to cause damage to the lubricating oil film, which leads to poor engine lubrication and wear of some parts, and there is also a certain probability of burning engine oil.

The amount of oil in the engine. If there is too much oil (above the maximum scale mark), the excess oil can easily enter the combustion chamber (internal pressure is too high) and gelatinous carbon deposits occur. Although there will be no obvious impact at first, the carbon deposits generated will definitely become more and more serious as time goes by, not only clogging the three-way catalytic holes, causing exhaust emissions to exceed the standard, but also burning engine oil in serious cases.

Because Volkswagen's cylinder walls store oil in a mesh shape, the residual oil in the mesh burns off when the piston is operating due to the increase in temperature. When this kind of cylinder is used in Europe, the speed of the vehicle will generally be faster due to the oil in Europe and the good road conditions.

It is normal for Volkswagen cars to burn engine oil, and the engine will burn oil, but the situation of various engines is different.
