Why does Volkswagen burn oil?

The reason why Volkswagen burns engine oil is solved in this way.

In fact, it is normal that not only Volkswagen cars burn engine oil, but other models also burn engine oil.

Four common reasons for burning engine oil

If you don't clean the oil circuit for a long time or if you don't clean the oil circuit effectively, using detergent at will and using effective detergent are two different things; 2. The replacement cycle of antifreeze is too long or not replaced at all; 3. The oil change cycle is too long; 4. Long-term or frequent short-distance driving. One or all vehicles burning engine oil at the above four points must be accounted for.

Engine oil combustion grade

According to the classification of serious engine oil combustion, below 2000, one liter is serious engine oil, 2000-4000 is medium engine oil, and 4000-5000 is light engine oil. According to the national standard GB/T 19055-2003, the consumption rate of engine oil at rated speed and full load shall not exceed 0.3%, that is, the lubricating oil per 5000 km 1- 1.5L is normal loss.

Harm of combustion engine oil

Subsequent hazards of burning engine oil: If it is delayed, more and more engine oil will be involved in the combustion, and finally the cylinder will be pulled. Because engine oil participates in combustion, there are many engine oil components in the mixture, and the three-way catalyst load is too large, so the three-way catalyst will be replaced in advance. Three-way catalysis is very expensive, which will lead to a sharp increase in costs. As a result of extending the service life of engine oil, the engine must be disassembled and overhauled, and the expensive three-way catalyst must be replaced in advance.

Finally, we should understand that the root cause of burning engine oil is that the oil circuit is not clean for a long time, which leads to excessive carbon deposition-too much carbon deposition leads to piston ring seizure. Therefore, to deal with such problems, attention should be paid to cleaning the oil circuit in time after the oil is repaired. To avoid burning oil again.
