What are the reasons for Audi's oil burning?

[MaliaDella]

Here are the reasons for Audi's oil burning: 1. Differences between domestic and international standards: When vehicles are produced domestically, modifications are made to suit the driving habits of Chinese consumers. During this process, oil burning issues may arise due to differences between domestic and international standards. 2. Carbon deposits: Carbon deposits easily form in the combustion chamber, and a large amount of carbon accumulates in the piston grooves. When the piston rings stick together, a sealing lock occurs, significantly reducing the oil seal's ability and blocking the oil holes, preventing normal oil circulation and increasing oil consumption. 3. Excessive clearance: This is also a condition that occurs during the production and design process. Audi's piston walls are very thin, making it easy for oil to enter the combustion chamber during operation. This leads to the main cause of oil burning. With oil present and a combustion method, oil reduction is inevitable. 4. Aging reasons: Corrosion and aging of the valve oil seals and aging of the front and rear crankshaft oil seals are also major causes of oil burning. Prolonged operation allows oil to enter the combustion chamber. Oil leaks further increase oil burning, and only regular inspection and replacement can solve this issue. 5. Other reasons: Damage to the oil seal between the turbocharger and intake pipe, high fuel content in the oil, clogged oil filter, clogged air filter, damaged or clogged exhaust valve, incorrectly installed piston rings, overfilled oil, and dirty throttle valves can all cause oil burning. Here are the solutions for oil burning: 1. Use high-quality oil: Oil is highly susceptible to corrosion and aging under prolonged high temperatures, causing the oil film to thin and more easily enter the combustion chamber to participate in combustion. Therefore, using high-quality oil can significantly delay this phenomenon. 2. Pay attention to the cleanliness of the fuel system: Carbon deposits are inevitably produced during fuel combustion, and carbon deposits are the root cause of some car failures, such as aging valve oil seals and increased piston-cylinder wall clearance, which are directly or indirectly related to carbon deposits. Therefore, keeping the fuel system clean is very helpful in preventing oil burning, although this requires the use of high-quality fuel additives. 3. Use external aids: As mentioned above, the cleanliness of the fuel system and the oil's anti-aging properties are key factors in preventing oil burning. Considering the current domestic fuel quality, it is necessary to use high-quality oil and fuel additives to achieve this, which is also the key to solving oil burning without disassembly and repair.
