20 14 Audi Q7 aggressive engine oil?

Burning oil is a common problem of many Audi models. As long as a car that burns engine oil has a certain fuel consumption, you think it's only your own opinion not to burn it. In fact, the shortage of engine oil exists objectively.

Most Audi Q7 cars burn engine oil because piston rings are stuck by carbon deposits. Adding high viscosity engine oil is only an expedient measure to prolong life. When the engine oil enters the combustion chamber to participate in combustion, it will form more carbon deposits, which will lead to the aggravation of engine oil combustion and form a vicious circle. If this goes on, it will cause cylinder wall strain and even cylinder explosion, and finally the engine can only be disassembled for maintenance.

At present, it is difficult to fundamentally eliminate the problem of engine oil burning, but effective cleaning oil circuit, carbon deposit and sludge can be used regularly in daily maintenance to avoid engine oil burning.

Four 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;

The replacement cycle of antifreeze is too long or not replaced at all;

The oil change cycle is too long;

Long-term or frequent short-distance driving.

One or all vehicles burning engine oil at the above four points must be accounted for.

How did the piston ring get stuck?

The principle of piston ring jamming starts from the oil circuit. The bearing temperature of the oil is 1 10℃. The high temperature caused by the long-term uncleanness of the oil circuit keeps the oil at the temperature of 120℃ or higher for a long time, so that the oil will be exhausted in advance and the small holes on the oil ring will be crusted and stuck by long-term baking. One cylinder stuck is 5000 kilometers per liter of oil. Therefore, to solve the problem, we must start with the root oil circuit, which is the way to get rid of the root.

Solution of engine oil combustion

In the habitual thinking of riders, it is always believed that burning engine oil requires overhaul, which not only bears high maintenance costs, but also bears unpredictable risks and depreciation losses caused by vehicle overhaul. Destroy the tightness and accuracy of the engine. Moreover, it is possible to burn oil after tens of thousands of kilometers, so overhauling the engine is unsustainable.

Now the demolition-free technology is very mature and gradually accepted by the majority of car owners. In particular, the fourth generation of Siyoupu nondestructive repair products completely got rid of the technical shackles of operating in the garage. Without removing a screw, the owner can operate it himself. When driving, the piston ring is loosened and the effect is remarkable.
