One fine day, the car may start to consume engine oil in some simply inadequate amounts. This can happen even with a relatively new car with a relatively low mileage. Correct diagnosis and appropriate measures will help get rid of problems. The motorist will be able to carry out a proper check on his own. Most likely, in such a situation, you will have to do decarbonization.
The most common cause of oil consumption today is aging and subsequent evaporation of the lubricant. The additives in the oil lose their useful properties as a result of use by the engine, as a result of which the lubricant simply begins to escape through the ventilation. So it gets into the intake manifold and cylinders, and already there it burns out together with the working mixture. The problem is that in most cases, burning grease simultaneously forms heavy fractions that accumulate on the oil scraper rings. This leads to a deterioration in their mobility. If the driver does not take appropriate measures in time, coking may occur - overlapping of the drain holes in the piston. As a result, the rate of consumption of lubricant in the engine begins to tend to the rate of fuel consumption.
Of course, there are many other problems associated with the emergence of a buttermilk. This is the forced force of the power unit, and even a loosely twisted candle. However, the most common cause is still coking.
It should be emphasized that independent accurate determination of the true cause of increased oil consumption is not an easy task. It is very often impossible to solve it with superficial methods. The best diagnostic method is vacuum. It requires a cylinder pneumatic density analyzer based on vacuum gauges. Before checking, the candles are removed, after which the device is connected to each cylinder in turn. With its help, the maximum vacuum in the cylinder is set. Based on the data obtained, conclusions are drawn about the degree of wear of the liners.

Another effective diagnostic method is endoscopy. A special camera is used for it. The device does not provide accurate data, and therefore the presence of an "experienced eye" is very important in troubleshooting. In any case, you will most likely not be able to make a high-quality diagnosis of the cylinders on your own. Better obabitsya on this issue to qualified specialists at the service station.

If the diagnosis is unambiguous - coking, then the cylinders will have to be decoked. For this, special liquid formulations are used. They are poured into each of the cylinders through a spark plug hole. The drug softens carbon deposits in such a way that the next time the engine is started, all the debris on the cylinders simply burns out without the next formation of heavy fractions. Perhaps decoking will have to be done several times in a row (each new time after a short trip), since the piston bottom is best cleaned in this way, but the rest of the structural elements are washed with labor.
Similar foams can be used as an alternative to liquid decarbonizers. Foam is applied in the same way and cleans somewhat better, however, it is likely that you will not be able to do with one single injection of the product.
Some drivers also advise using "folk" remedies, including Dimexide. This drug is available over the counter at the pharmacy. However, it should be remembered that Dimexide is extremely aggressive and its use in the engine may have some side effects.
