The Audi Q7 burns oil for 1200 kilometers after maintenance

In order to protect the engine and prolong the life of the engine, Audi cars are designed to reduce the frictional resistance between the piston ring and the cylinder wall, and an oil film will be formed in the cylinder wall, and part of the oil film will be burned off with the gas burned at high temperature, so the oil loss is more than the same period last year.

1. The processing technology of the engine cylinder of Audi car, the engine cylinder wall is shown as a mesh under the microscope, and each small mesh is a "small oil depot" for storing oil, and the piston has better lubrication performance than the flat cylinder wall when running up and down in the cylinder, which also minimizes the wear between the piston ring and the cylinder wall.

2. The toughness of the piston ring of the Audi car is better, and the degree of tension is weaker than that of the Japanese car, simply put, it is strong, but the elasticity is small, and this matching naturally reduces the wear and tear caused by the piston ring running up and down on the cylinder wall, so the Volkswagen car has traveled hundreds of thousands of kilometers to measure the wear of the cylinder wall of the engine, which is much smaller than that of other car series, and the engine can still maintain good working condition.

3. The engine is like the heart of the car, the engine burns oil in the final analysis, or the piston ring has a problem, under normal circumstances, there is no oil loss of 1000km, if it exceeds too much, it is possible to burn oil. If there is a problem with the sealing of the piston ring, the oil will follow the movement of the piston and secretly drill into the combustion chamber to participate in the combustion, and then the oil will be burned.

4. In order to prolong the service life of the engine, Audi car manufacturers burn engine oil.

Precautionary measures for burning engine oil:

1. Use high-quality engine oil

Engine oil is very easy to corrode and age in a long-term high temperature state, resulting in the oil film becoming thinner, and it is easier to escape to the combustion chamber to participate in combustion, so the use of high-quality engine oil can greatly delay this phenomenon.

2. Pay attention to the cleanliness of the fuel circuit

Fuel is indispensable in the combustion process to produce carbon deposits, and carbon deposits are the root cause of some car failures, such as the aging of valve seals, piston cylinder wall clearance, etc., all of which are directly or indirectly related to the formation of carbon deposits, so keeping the fuel circuit clean is of great help to prevent burning engine oil, of course, this needs to be done with the help of high-quality (PNF) fuel additives.

The engine oil itself has a certain amount of consumption, and excessive consumption is the problem of burning engine oil. There are many factors that affect the burning of engine oil, such as: fuel quality, driving conditions, driving habits, maintenance habits, etc., the above reasons will aggravate the oil consumption and lead to the burning of engine oil, making the vehicle appear:

1. Carbon deposition occurs in the combustion chamber, which makes the gas ring of the piston ring stuck, and the sealing is poor.

2. Oil sludge is generated in the lubrication system, and the oil sludge blocks the oil return hole of the oil ring and weakens the oil scraping performance.

3. Wear occurs between the piston and the cylinder wall.

4. The valve seal is corroded and aging, and the sealing performance fails.

In addition, cars now have crankcase ventilation systems (exhaust valves), which can also exacerbate oil consumption if there is a problem. In the past, the problem of burning engine oil could only be solved by dismantling and repairing, but now there is a plan to solve the problem of burning engine oil without dismantling and repairing, which can be understood by taking a look.

Hello, burn oil seriously need to check the turbocharger, PCV valve.

Look at the supercharger, it's possible it's broken.

Engine operation requires lubrication, and it is normal for the lubricating oil applied to the cylinder walls to be burned off in very small amounts.

The engine is worn out to a certain extent, after 1000 kilometers, and the oil consumption exceeds the liters, it needs to be repaired.

Engines go through this process. The 07 Audi Q7 is no exception.

For the old Audi Q7, this is all about looking at the specific vehicle situation, and it is not very good to determine whether there is a problem.

A normal gasoline engine does not burn oil.

Audi Q7 burns engine oil very seriously, how to repair it?

It is normal for German cars to burn engine oil, and if the oil consumption is too much, it needs to be paid attention to. Otherwise, it will increase carbon deposition and contaminate the oxygen sensor and three-way catalytic converter, resulting in substandard exhaust emissions.

Burning engine oil is nothing more than the following: easy first and then difficult.

First, a faulty exhaust valve can lead to excessive oil consumption.

Second, the turbocharger, the turbocharger has a very high working temperature and very harsh working conditions. Therefore, it needs high-quality fully synthetic motor oil to provide lubrication and heat dissipation protection.

Third, the valve oil seal is aging or worn. When the valve oil seal is unable to effectively scrape off the oil attached to the valve stem, the oil will enter the cylinder and burn. solution, replace the valve seal.

Fourth, the cylinder liner and piston ring are seriously worn, and the clearance is too large. Or the carbon deposit is serious, the piston ring is stuck in the ring groove and so on. It is advisable to use an endoscope to check the carbon deposits in the cylinder. The solution, clean up the carbon deposits, re-boring the cylinder, and replace the improved piston rings.

Audi Q7 uses a turbocharged engine, the power of this engine is relatively large, and the fuel consumption will be correspondingly lower, but the requirements of this engine for lubricating oil are relatively high, only high quality, high temperature resistance, and high cleanliness of lubricating oil are more suitable, and if Audi Q7 burns engine oil, it is likely that due to the poor sealing of the oil seal, the exhaust gas re-enters the lubrication system of the engine, so that the cleanliness of the oil inside decreases, the pressure gradually increases, and the consumption of oil begins to become excessive. In this case, the entire oil lubrication system should be investigated, the carbon deposits remaining from combustion should be clear, and the intake and exhaust valves should be unblocked, and the aging and damaged valve oil seals and crankshaft oil seals should be replaced, and finally the gap between the engine blocks should be further reduced to keep the engine temperature from being too high.

The common causes of engine oil burning are mainly the gap between the engine block, the piston ring sticking a large amount of carbon deposits and wear, the corrosion and aging of the valve oil seal, the corrosion and aging of the front and rear crankshaft oil seals, which are greatly affected by the engine temperature and oil temperature.

**。How to solve the problem of burning engine oil in Audi Q7. Original.

The common causes of engine oil burning are mainly the gap between the engine block, the piston ring sticking a large amount of carbon deposits and wear, the corrosion and aging of the valve oil seal, the corrosion and aging of the front and rear crankshaft oil seals, which are greatly affected by the engine temperature and oil temperature.

Audi Q7 uses a turbocharged engine, the power of this engine is relatively large, and the fuel consumption will be correspondingly lower, but the requirements of this engine for lubricating oil are relatively high, only high quality, high temperature resistance, and high cleanliness of lubricating oil are more suitable, and if Audi Q7 burns engine oil, it is likely that due to the poor sealing of the oil seal, the exhaust gas re-enters the lubrication system of the engine, so that the cleanliness of the oil inside decreases, the pressure gradually increases, and the consumption of oil begins to become excessive. In this case, the entire oil lubrication system should be investigated, the carbon deposits remaining from combustion should be clear, and the intake and exhaust valves should be unblocked, and the aging and damaged valve oil seals and crankshaft oil seals should be replaced, and finally the gap between the engine blocks should be further reduced to keep the engine temperature from being too high.

Audi cars generally have the situation of burning engine oil, if your car is already a serious situation of burning engine oil, then this problem is basically difficult to solve, because you can't replace the engine, so you can only add oil frequently, or adjust the oil model slightly higher by a level, so that the phenomenon involved is slightly better, but there is still no way to solve it, since you choose this car, then it can only be like this, or consider selling the car for a new car to drive.

If the Audi Q7 is always serviced in the 4S shop, then consider whether it is the reason for the engine design. If so, then it is recommended to change the car, because with our current process, it is estimated that it is unrealistic to use maintenance to change the engine to burn oil.

If it is caused by improper use of lubricating oil, improper maintenance, gasoline oil, etc., it is recommended to replace an engine by condition, 2 replace a disassembled engine, 3 is the last choice to disassemble the engine for maintenance.

If the vehicle burns oil seriously after driving more than 100,000 kilometers, it has to disassemble the engine for overhaul.

It is normal for German cars to burn engine oil, this depends on what extent, if it is too serious, it will only overhaul the engine, I hope it will be useful to you.

Audi Q7 burns engine oil seriously and the general ways to solve it are:

Return to the factory to repair the engine.

Change the oil label and make it higher to slow down the burning of oil.

Audi Q7 burning engine oil is more serious, but it is only limited to the old model, and now the optimization of the ** model is OK.

A common problem with VW. Every day, 60% of the oil is burned here, and 80% is owned by VW. You understand what that means, right?

Let's change the car, and the principle VW will be in the future

The engine will only burn oil when it is worn to a certain extent.

Burning engine oil refers to the state of running for 1000 kilometers and the cumulative consumption of engine oil exceeds the liters.

The fault of burning the engine oil can be solved by repair.

If the maintenance operation is strictly in accordance with the requirements of the "instruction manual", it can reduce the number of failures and postpone repairs.

Engine overhaul is recommended.

Audi car series burning engine oil is a common problem, if you want to be thorough**. Generally, only the engine overhaul is carried out. Hengkong.

I hope Muhong mine is useful to you, and I wish you all the best.

This is a blind and crude phenomenon of burning engine oil.

Oil reduction is very common for Volkswagen cars, and it is recommended that you go to the repair shop in Weimo to find out the cause of the oil burning, which may be turbocharging or the exhaust valve. Thank you.
