Is it really the engine problem that German cars burn engine oil?

The causes of engine oil burning in German cars and how to prevent them.

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.

The cylinder wall of the German car engine will form a net-like groove on the surface during machining, of course, this groove cannot be seen with the naked eye, and can only be seen with a special microscope. The function of the groove is to store the oil, so that the lubrication performance of the piston when running up and down in the cylinder is better, so that the wear between the piston ring and the cylinder wall is minimized.

Another point is that the piston ring toughness of German cars is better, and the tension is relatively weak, which reduces the wear caused by the piston ring running up and down on the cylinder wall.

Combined with the above two reasons, although the wear of the cylinder wall is reduced, it is inevitable that part of the oil enters the cylinder, resulting in the situation of burning the engine oil. In other words, there is only one choice between increasing the wear and tear on the cylinder walls and burning the oil, and there is no doubt that the German car chose the latter, in fact, in order to make the engine last longer. Those ideas we had in the past were actually wrong to blame others.

There are many reasons for burning engine oil, which has a lot to do with the assembly and performance of the engine itself.

The car has become a means of transportation for many families, and the car has brought us a lot of convenience, which not only reduces the inconvenience caused by our travel, but also saves a lot of time. There are countless car brands on the market now, including domestic, Japanese, and German. I believe everyone is curious about such a question, German cars generally burn engine oil, which is also something that everyone knows, but why are so many people still willing to buy German cars?

What are the advantages of German cars?

As we all know, as long as the engine is moving together, the cylinder and piston will reciprocate in motion. When gasoline is burned in the cylinder, it will inevitably produce the phenomenon of thermal expansion and cold contraction. Therefore, there will be a certain gap between the cylinder and the piston in the engine design to prevent the cylinder or piston from wearing.

In order to extend the life of the engine, the cylinders of German cars are generally designed in the shape of a mesh. The advantage of this is that every time the piston reciprocates in the cylinder, a film of oil adheres to the cylinder wall, reducing engine wear. In addition, the gap between the piston ring and the cylinder of the German engine is larger than that of the Japanese and American engines.

According to this design, it is normal for a small amount of oil film attached to the cylinder lining to volatilize and burn.

Germany has always been a world leader in car body technology, and Jetta and Santana are still in the top 10 of the monthly sales list. If there is no good quality as the foundation, it is difficult to have such vigorous vitality. Most of them are good workmanship, hard workmanship, strong body, conservative and introverted, durable, advocating maintainability and reliability, pursuing speed, etc., and pursuing every detail.

German cars have always been an indispensable key structure of the world's auto market, and the release of new cars under German car brands every year will surely lead the trend of the auto market at that time.

The appearance of German cars is stable, the technology has always been in a leading position, the quality and workmanship of the car are better than other brands, which is also the main reason why everyone knows that German cars burn engine oil and will choose German cars.

The phenomenon of burning engine oil is common in German cars, and the reason why there are so many consumers buying is that German cars are of high quality and low price, and at the same time, German cars are a joint venture brand, so the phenomenon of German cars burning engine oil will not prevent domestic consumers from buying this brand of cars.

German cars since entering the Chinese market has attracted the attention of domestic consumers, the early days of China's own brand car manufacturing technology is not very advanced, so German cars occupy a dominant position in China's automobile market, so people's concept of German cars is still deep-rooted, but German cars have the phenomenon of burning engine oil, but the sales of German cars in China are still very high, the reason is that German cars are cheap and cheap, and the concept of this joint venture brand has produced a good impression in people's hearts. Naturally, German cars are selling well in China. <>

German cars are of good quality and low price.

In many joint venture brands, the German car is indeed cheap, the German car and the Japanese car to compare, the German car is often much lower than the Japanese car, and the German car dealers in order to make their own car sales better, so targeted to create a Chinese German version of the car, because many domestic consumers like the appearance of the fashionable car, and at the same time increase the publicity concept so that the German car brand in the consumer has an indelible impression, Well, in this case, German cars naturally sell well in the domestic auto market. <>

The German car is a joint venture brand.

The reason why domestic consumers are still keen to buy German cars is that German cars are joint venture brands, because in the early days of China's automobile manufacturing technology is not very advanced, so German cars entered the Chinese market very early, and now many consumers are infinitely praising the good German cars, but they ignore the current independent brand cars, which leads to the unstable development of China's independent brand cars.

In general, there are still many consumers who buy German car burner oil, the reason is that German cars are of high quality and low price, and the concept of joint venture brands is deeply rooted in the hearts of consumers. However, the current self-owned brand car manufacturing technology is advanced, and the car is no worse than the joint venture model in all aspects. <>

The German car burns oil very well, but it is still good in other aspects, the quality of the car is still good, the performance is good, there are not so many small problems, and it is also the reason why many people choose it.

Because for the same ** car, this car is still very cost-effective. I believe that as long as we take good care of it, this phenomenon should be reduced.

Insiders said that in terms of power, it is not lost to other models in the same class, among which several well-known models Audi RS6 series, R8, RS6 series, etc. are Audi's representative cars. Not only that, as a private car, it is equipped with a configuration that fully meets the needs of family cars, even if it is used as a business car to welcome VIPs, it will not lose face at all, and even add a strong aura to the owner.

Because the oil storage structure of the German car engine is not the same, it uses a design similar to the anilox structure, which can make the cylinder seepage wall adsorb more oil, so that the piston ring is easy to form an oil film when it moves, so it has a better lubricating oil effect, but the loss of oil is also greater, so the German car will also burn the oil.

As of September 2019, German cars have changed the production process of the engine, and a breakthrough has been made in response to the problem of burning engine oil, so the degree of burning engine oil has been greatly reduced.

Generally speaking, the oil needs to be changed every 6,000 kilometers or so when the car has been driven. Engine oil has the effect of cleaning, cooling and lubricating the engine, and changing the engine oil can make the engine work better.

When changing the engine oil, the car must be replaced with the same kind of engine oil, and the engine oil of different brands and labels cannot be mixed, otherwise it will affect the work of the engine, and the engine will be damaged in serious cases.

It is normal for a car engine to burn oil, and if the oil loss is low, you don't need to pay attention to it. If the degree of oil burning is more serious than volt disturbance, you have to go to a repair shop or 4S shop to ask a professional to check and repair it to prevent unnecessary trouble.

German cars are well received by many car lovers due to their relatively high value retention rate, rich configuration and relatively durable characteristics.

So what about burning engine oil, it means that the car exceeds the normal consumption of engine oil, and the standard defined by our country is that 1000 kilometers shall not exceed the consumption of oil in liters.

We have to understand that not all oil consumption is called burning oil. Because the engine itself cannot fundamentally eliminate the consumption of engine oil. Everyone should have experienced such a life scene, a greasy plate or bowl, you use a spoon or even a knife to scrape, the oil will never be clean.

It's like two oil rings on a piston that can never scrape the oil off the cylinder wall.

Under normal circumstances, the phenomenon of "burning engine oil" in the car will damage the vehicle's oxygen sensor too quickly, resulting in an increase in carbon deposits in the combustion chamber, unstable idling, weak acceleration, increased fuel consumption, and excessive exhaust emissions. In severe cases, the engine lubrication is insufficient, which causes irreparable damage or even scrapping of the engine, resulting in a significant increase in maintenance costs and even potential accidents.

If your car burns oil, the symptoms are mild, when the car has run about 1000-2000 kilometers, there is more carbon accumulation in the exhaust pipe, and the oil shown on the oil scale is already below the normal scale, or it is no longer visible. Then the burning is serious because the exhaust pipe has already emitted blue smoke.
