The problem of burning engine oil.
At the beginning of last year, during maintenance, I found that the engine oil was burning, and I thought it was a shortage of engine oil, but the repairman confirmed that the car did have a problem with burning oil. Despite regular maintenance and replacement of wearing parts, the problem persists. To cope with this, I always have 1L of oil in the trunk.
Later, I began to pay attention to the changes in the oil dipstick, and I maintained it twice a year, and replenished the oil about one liter every 4,000 kilometers. But at the end of last year, the burning of engine oil became more serious, and the oil needs to be replenished every 2,000 kilometers or so, which will cause even greater problems.
The problem of burning engine oil gave me a headache, and I contacted the repair shop to learn that it may need to be overhauled, which cost about 8k, although the car has run more than 190,000 kilometers, but there is no other abnormality except for the problem of burning engine oil. Considering that other problems may arise after the overhaul, I decided not to carry out the overhaul and not disassemble it as long as it does not affect the normal driving.
Identifying the oil burn problem requires the exclusion of other factors.
Initially a factory wastegate was replaced, but it didn't improve the problem. After that, the oil seal was replaced, which cost more than a thousand pieces, but the problem persisted. In the end, the turbine was replaced, and the problem was still not solved. Upon further inspection, it was found that piston ring seizure was the cause of the oil burning problem.
Ask the canal to be as clear as promised, only the source of living water comes.
Find the source of the problem, then to find a solution to the fundamentals, and finally find a brief explanation of how the piston ring is stuck: the treatment principle of piston ring stagnation should start from the oil circuit, the oil bearing temperature is 110 degrees, and the oil circuit is not clean for a long time caused by the high temperature, so that the oil is 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, and a cylinder stuck is 5000 kilometers of a liter of oil, at this time, the working conditions of other cylinders will also begin to be bad, and soon 4 cylinders will be stuck, 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. According to the IP of the brief description, it turned out to be a store that made additives. Although the analysis is very reasonable, it is still unknown whether it can solve the problem of whether I can completely cure my burning oil, so I asked the customer service of the store in doubt. After consulting and in-depth understanding, I feel that the hope of managing the problem of burning engine oil seems to be great, under the introduction of customer service, and after careful consideration, I purchased the store's support guarantee activities**, here is not impulsive consumption, I admit that I have gambling ingredients, in case it is not good, it can only be overhauled.
Start Cleanup + Repair.
Because the accessories that should be replaced before have been replaced, the inspection that should be done has also been done, and the next thing is to use it according to the suggestions of customer service, this product is divided into two kinds, one is to add engine oil, one is to add gasoline tank, a tank of oil needs to be added to three Si Youpu fuel repair agent at a time, and a repair agent of engine oil is added to the engine oil at a time, and each tank of oil is added, and so on, according to the customer service instructions for 6 times in a row can basically be done (participating in this bottom activity is still very cost-effective, cost-effective, so buy something first consult customer service really unexpected surprises) 。 All that's left is to drive more during the repair period;
Four tanks of oil are not long, not short, and in a blink of an eye it is time to "witness the miracle" and the four tanks of oil ran a total of 19559 kilometers, an average of 488 kilometers of a tank of oil, really in addition to burning the rest of the oil is really good, I hope to solve my heart disease.
As you can see from the above, you can clearly see the cleaning effect from these images, and my most intuitive feeling is that the ignition is smoother, the vehicle power has also improved, and the smoothness of the throttle has also been greatly improved compared to before. But these are not the most important things, the most important thing is the consumption of the oil. Compared to before, the oil consumption of four tanks is now very stable, and it is no longer necessary to add oil every 2,000 kilometers as before. Because I participated in the bottom support activity, the customer service also gave me 6 fuel additives for free, which was used to consolidate the cleaning effect at the end.
It's been a year, and after two new maintenance cycles, the current oil consumption is stable, and it is impossible to say that it is impossible to do it without consumption. 7000 kilometers of maintenance consumes half a liter, and the state of the new car is almost meaningful, and when the oil was burned before, it is a great improvement.
