German cars have always been recognized for their quality, and the fact that your vehicle has performed well for the past seven years without any problems is a testament to its stability and driving feel. For many men, they treat the vehicle with affection as if it were their partner, seeing it as a part of life. My big white purchase and September 2015, the classic Q5, the third generation EA888 nose, a total of nearly 100,000 kilometers, 7 years of conscientious work, never had a problem, whether it is stability or driving feeling, very good. I have to say that the quality of German cars is still very good. I was engaged in the matter of burning engine oil, and at the beginning of the year, a rider gave me a suggestion, and now that I think about it, I am still very grateful for his advice.
I also uploaded the driving book to avoid being mistaken for a water army
In fact, it doesn't matter whether it is a water army or not, the key is to solve the problem by spending money. If there are some good things, promoting them can also help more riders.
The following is the text, Dabai probably ran about 72,000 kilometers and began to feel that the oil consumption was a little large, after the maintenance ran 3,700 kilometers of oil alarm, and then ran to 1,500 kilometers of oil alarm, at this time the oil burning was serious, during which the exhaust valve was also replaced, thinking that it was a common problem of Audi cars, and various inspections were done, all to no avail. The car burns engine oil seriously, and people also suffer from oil anxiety, and they always think about it.
There are a total of three cars in the family, one in 2011 CC, also 230,000 kilometers, still normal, and the oldest one is the 2005 Corolla, which is already 300,000 kilometers. But at present, this Q5 runs the least, and I guess it may be that it is not usually driven much, short-distance driving, and even the quality of gasoline. Referring to the information of the post of the rider, I learned that although the piston ring of the third-generation EA888 engine has been improved, it still cannot avoid burning engine oil, but it is a little later than the second-generation EA888.
At the same time, according to the same idea, the internal combustion chamber of the engine was first inspected, the cylinder wall was intact, the reticulation was clear, and there was no wear, but the top of the piston was miserable, with thick carbon deposits, and even thick carbon deposits on the valves. The master of the 4S shop said that the fuel injector is most likely to be blocked, and it cannot be completely atomized when injecting, which affects the power and increases fuel consumption.
Inside the combustion chamber, thick carbon deposits on the pistons
Since you have found the problem, you can focus on solving the problem, and you can get twice the result with half the effort. With the hands-on practice of riders, there is no need to worry about any problems. I took quite a lot of photos during the whole process, one is to effectively record the repair process, compare each repair with the last one, and also help other car owners.
The process of repair has become a travelogue, take advantage of the free time, by the way to play a lap, customer service said, continuous running at high speed is more suitable for removing carbon deposits, and after adding the repair agent, you must use up this tank of gasoline in time to ensure that the gasoline and repair agent do not deteriorate. Here are two key words, "continuous" and "high-speed", whether it can effectively and quickly remove carbon deposits, these two points are also very important. There is an old folk saying that Shanxi is seen on the ground, and Shaanxi is seen underground. Shanxi is one of the birthplaces of Chinese civilization, and it was the Jin Kingdom in the Spring and Autumn Period, so it is referred to as Jin. The long history has left a lot of cultural heritage, the ancient Shanxi commercial capital has a long history, the Jin merchants operate the salt industry, ticket number and other businesses, especially the ticket number is the most famous, coupled with the complex topography, rivers and mountains to form the natural landscape, tourism resources are very rich. engine start, let's go!
Before you go, record the number of kilometers, check the oil level, add the right amount of oil repair, then head to the gas station and add three gasoline repairs at the same time. This is done because the vehicle burns a lot of oil, and the use of both oil and gasoline repair can be used to achieve a quick effect, improve the effect, and achieve a more thorough cleanup. It's like injecting a dose of medicine into a terminally ill person and giving new life to life.
Before departure, the vehicle is filled with fuel and equipped with fuel repair agent, and a tank of oil is added to three general fuel repair agents

In the process of adding the repair agent to the engine, one maintenance can be added on Monday, a total of two maintenance cycles.
When the oil level is normal and the dipstick level is reconfirmed, the mechanical dipstick is the most accurate measurement tool.
Kilometers recorded at the time of departure.
The mechanical dipstick is the most accurate measuring tool Pingyao Ancient City is located in Pingyao County, Jinzhong City, Shanxi Province, was built in the period of King Xuan of Zhou, expanded in three years of Hongwu in the Ming Dynasty, and has a history of more than 2,800 years. This ancient city has well retained the basic features of the county seat in the Ming and Qing dynasties, and is one of the most complete ancient cities in the Han nationality region of China. The ancient city of Pingyao is known as one of the "four most well-preserved ancient cities", and it is also one of the only two ancient cities in China to have successfully declared the entire ancient city as a world cultural heritage.
Guanfeng Building is located in Hengjie County Yawai Street up and down two floors, the first floor is a brick platform, the second floor is a wooden building, and the middle is a brick coupon door opening. Standing on the Guanfeng Tower, the scenery of Yamen Street is in full view. On the right side is the yamen, and on the other side the street scene is lined with shops, a peaceful scene.
Quaint streets.
Walking through the ancient city and navigating the ancient streets is like stepping back in time. Modern civilization seems to be far away, the shops on the street are small and quiet, there is no **, only a classical woman sitting quietly on the side of the counter, or an old woman in a blue shirt, guarding the counter that is not a ruler, and a few handmade rings are placed in front of her, small and exquisite to the point that you can't bear to touch, as if you are guarding an old age. It is a pity that some of the ancient buildings in the ancient city are being repaired for a long time, and they cannot enjoy the scenery of the ancient city intact.
On the way, we also went to the famous Qiaojia Courtyard in Shanxi, Yangcheng Imperial City Xiangfu, Guoyu Ancient City and other scenic spots. The travelogue is just an appetizer in the post, and the focus is on the restoration process.
After getting home and tidying up, I couldn't wait to check the dipstick. The color of the oil has obviously darkened a lot, but the fluid level is still normal. Worried that the inside of the engine oil was mixed with a large amount of carbon deposits from cleaning, I did the maintenance in time. I bought it before and maintained ** just in handy. Personal experience is that it is necessary to do maintenance in time after repair, even if it is not enough to maintain the mileage at all. It may be that the oil can still be lubricated normally, but because the filter is filtered, a large amount of carbon and impurities may clog the filter and make the filter ineffective. So I think the benefits outweigh the disadvantages.
In addition, the maintenance interval can be appropriately shortened according to the actual road conditions. For example, in the case of abnormal congestion in the city, the engine will not stop running even in traffic jams, so the maintenance interval can be shortened appropriately. However, it is not recommended to maintain the car once a year, because after the oil is opened, it is constantly lubricated and circulated in the engine, and it is a high-temperature operating environment, and the operating temperature of the turbocharged engine is higher, which tests the quality of the engine oil. Therefore, even if you run very little, you must maintain it according to the principle of time or kilometer, which comes first.
As it turns out, my guess was correct, the oil has become like "soy sauce", looking dark and sticky. But it also shows that the effect of this long trip is very significant, and the black oil is mixed with a lot of carbon deposits that have been cleaned. If the oil and filter are not changed in time, it may lead to carbon deposits and scabs, clogging the oil return hole, and piston ring stagnation.
After about 3,000 kilometers round trip from Shanxi, the oil became as black as soy sauce after continuous repairs, and the amount of oil pumped out was quite normal.

There is a lot of black powder on the exhaust pipe with the metal color of the piston, which is somewhat viscous, which should be a manifestation of carbon deposition and exhaust gas, and also shows that the repair agent has played a role. Figure below.

The on-board computer shows that the liquid level is normal.
The number of kilometers when you get home is shown in the map below.
The kilometers at the start were 93,895 km and 96,889 km when returning, covering about 3,000 km.
Add new engine oil, confirm the oil level, prepare to add a new bottle of repair agent to the engine oil, drive the car to the repair shop, explain the situation to the receptionist, and enter the workshop, wanting to check the repair effect and take photos to collect materials. The workshop is very tidy, and I deliberately chose a working day for maintenance to avoid queues. There are enough stations in the workshop, and the receptionist fills in the list and drives the car directly to the station, which is pumping oil.
The conscientious technician also cleaned the engine compartment by the way after completing the maintenance, which looked very comfortable. In the past seven years, the maintenance of the vehicle has been very good, which is inseparable from my careful care and the service of professional technicians in the 4S shop. It can be said that I would rather spend money on maintaining my vehicle than saving money.
The second time it drove Lianyungang and Yantai, a total of 2,000 kilometers. Going to the beach in the summer and enjoying a seafood barbecue and beer is really a great treat of life. I don't care how much money I have, I only care about how many years of youth I have. In the past few years, the pandemic has changed my perspective a lot. I used to think that work and career were the most important things, but now I think that spending time with my family and health are the most important things. Make an appointment with a friend and go!Still at the same gas station, three repairs were added before refueling.
During the trip, I felt that the scenery along the way was very beautiful, and while I was still young, I wanted to feel the air of each city, experience the humanity of each city, and appreciate the scenery of each city. The first stop is Yantai, first go to a distant place, and then go to Lianyungang on the return trip, so that I will not feel regrets when I leave the first place, but there are some small expectations on the way home, because there is still the next place waiting for me.

Fresh prawns and juicy abalone, I swear I definitely didn't drive to sum up.
In total, the two trips covered more than 5,000 kilometers, mainly to use the summer vacation time to travel, but also to better repair the vehicle. During this 5,000-kilometer journey, I used five sets of gasoline version of the repair agent and two engine oil version of the repair agent, which basically solved the problem of burning engine oil.
I was skeptical at first, but after searching for related posts online, I found that many people have encountered similar problems, and the effectiveness of the use of the repair agent has been confirmed. Although I am not a professional, I have operated and repaired according to the experience of other car enthusiasts, and for someone who doesn't know much about cars, this repair method is also feasible and affordable. I spent about 2,000 yuan in total, which basically solved the problem of burning engine oil, and also made me feel at ease about oil anxiety.
During the repair process, the vehicle will shake slightly, and a large amount of black powder will be discharged from the exhaust pipe after high-speed driving, and a small amount of oil will rise. After consulting customer service, they said that these phenomena basically have no major impact. However, I personally believe that it is important to maintain and change the oil and oil filter in time after the repair. During maintenance, I noticed that the oil filter was blackened and the oil was sticky, indicating that a lot of carbon deposits were indeed removed. If repairs are not carried out in a timely manner, previous efforts may be wasted. I noticed that other riders also carried out maintenance in time after the repair, and since I drove more mileage, I carried out maintenance twice during these two repairs.
As for the reason for burning the engine oil, it has been described above, but this is just my personal guess. I've never used any additives before, and I always feel like it's an IQ tax, just an extra cost. But in the process of restoring the burned oil, I recognized the need for additives to keep the oil circuit clean and stop carbon deposits from developing.
In addition, be sure to replace the gasoline filter in time during maintenance. When there is a phenomenon of burning engine oil, we must pay more attention, and we cannot just rely on adding engine oil to prolong the service life. If left untreated, the problem will only get worse and may even lead to a situation where one liter of oil is consumed for every few hundred kilometers driven. With the intensification of burning oil, the carbon deposit will also increase, the valve is not closed tightly, the carbon deposit on the top of the piston is thickened, the compression ratio is changed, the oil ring return hole is blocked, stuck, and even the carbon deposit exceeds the piston edge, which will scratch the cylinder wall with the high-speed movement of the piston, and even lead to serious cylinder pulling problems.
To quote a sentence from other riders, replace maintenance with maintenance, and abandon the old thinking of car maintenance. Hopefully, this not-so-professional post will help riders with similar problems. Usually be sure to maintain and clean the oil circuit, which can greatly slow down the occurrence time of burning engine oil. If the oil burns out, you can use a PNF cleaner to keep the oil circuit clean. Don't be like me and just burn the oil before rushing to fix it, it will cause a lot of damage.
In addition, burning engine oil is not only the piston ring, but also the waste gas valve, to replace the original waste valve, otherwise it is not good to spend money in vain, confirm the piston ring problem, to check the cylinder pressure, the cylinder pressure is enough to disassemble the machine, the remaining problem is the piston ring. If the cylinder pressure is not enough, the machine may have to be dismantled. At present, it has been repaired for a year, 2 + 12 Division has * Pu this kind of repair is suitable, the actual hand is 2 + 18, an average of less than 90, do a dry ice carbon removal alone does not solve the problem of burning engine oil, but also 1000, this whole set of more than 1000 piston ring burning engine oil solved. It has been two maintenance cycles from the beginning of the year to the present, 7000 kilometers to change the oil, and the consumption is around half a liter.
