How about the 2015 Audi A4L1 8T still burns engine oil

Audi cars all have the problem of burning engine oil.

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. Burning engine oil is caused by the following factors, as long as the following problems are solved, burning engine oil can be solved.

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.

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.

If the maintenance operation is done properly, the failure of burning engine oil may occur after 100,000 kilometers of operation.

The problem of burning engine oil can be solved by repairing.

The 17A4L is equipped with Volkswagen's third-generation EA888 engine, the EA888 piston is made of aluminum alloy, the cylinder block is made of cast iron, the expansion coefficient of aluminum is three times that of cast iron, and the piston expands greatly in the specific environment of EA888 high temperature, so the non-working state matching gap in the design should be enlarged. It is precisely in this way that the engine oil should use 5w40 oil with higher viscosity at low temperatures to ensure that the combustion chamber is sealed. In order to improve the efficiency of the engine, EA888 uses a high-temperature turbine to increase the engine speed, when the turbine intervenes in the work, the engine temperature can reach 900 degrees, and the turbine speed can reach 200,000 rpm, so in this high temperature situation, the oil must pass the high HTS high temperature and high shear viscosity to ensure the sealing of the combustion chamber.

If the HTHs of the engine oil cannot reach the above, the performance of the engine oil will accelerate the attenuation, resulting in the wear of the parts, the reduction of sealing, the burning of engine oil, and the loss of power. Based on the above reasons, the most important thing for EA888 engine maintenance is to find the right engine oil suitable for this engine: first, to choose a fully synthetic engine oil with a viscosity of 5w40 Second, to choose an oil with a higher total base number to neutralize the acid base in the gasoline and slow down the deterioration of the engine oil, third, to choose the ACE (European Automobile Manufacturers Association) standard engine oil, the reason is very simple, there are many engine oil standards in the ACEA, which is proposed by one of the members of the association, the "Volkswagen Group".

Fourth, to choose a motor oil with a higher high-temperature shear viscosity than HTS, the same ACEA A3 B4 standard requires HTS >, which is also proposed by Volkswagen.

Audi will burn when it reaches a certain age, and the oil will burn if it is not wear-resistant, and if it is not repaired, it will burn the oil. Don't go for an overhaul yet, you'll be slaughtered, try the super American eutectic engine oil.

Hello, now Audi ** basically does not burn engine oil.

Hello! If it is not turbocharged, it rarely burns oil.

Hello friend. Burn two liters per 5000 km.

How can you call the public if you don't burn engine oil?

First of all, it is not the burning of engine oil, but the problem of engine oil consumption; The oil consumption of the Audi A4L is fully in line with the national standards in this regard; And at present, after the third-generation EA888 engine equipped with **A4L, the situation of large oil consumption is much better than before.

7000 kilometers of electronic ruler less than half of the usual like intense driving is this considered burning engine oil?

The new EA888 engine no longer exists.

In fact, to be precise, the loss of engine oil is larger, and the oil loss is much more normal than the increase in engine oil. And now the new EA888 engine is free of oil loss. We hope you have chosen the car you like.

Volkswagen's previous engines burned oil and superchargers. It is mainly caused by improper use. The first is to use semi-synthetic or fully synthetic motor oil.

In addition, do not stop the car immediately after driving the highway, and wait for two minutes before stopping the car after idling. Or the last few hundred meters without refueling, let the supercharger rest first. The supercharger is cooled by the oil, and there will be a little oil consumption.

Generally acceptable.

Let's see which generation of engine it is, if it is the second-generation EA888, it will definitely burn, and if it is the third-generation one, it is estimated that it will be a little better.
