Does Audi Still Burn Engine Oil?
2 Answers
Audi does burn engine oil. Preventive measures for oil burning: Use high-quality engine oil: Engine oil that is exposed to high temperatures for extended periods is prone to corrosion and aging, which thins the oil film and makes it easier to enter the combustion chamber and participate in combustion. Therefore, using high-quality engine oil can significantly delay this phenomenon. Main causes of oil burning: Poor cylinder sealing is the primary cause of oil burning. Poor cylinder sealing is mainly due to excessive clearance between the piston and cylinder wall, improper installation or poor sealing performance of piston rings, allowing oil from the cylinder wall to enter the combustion chamber, leading to fuel combustion. Poor sealing performance of valve seals, damage to the crankcase ventilation valve, or blockage of the crankcase exhaust port can cause excessive pressure in the crankcase, resulting in oil entering the combustion chamber along with crankcase gases.
As a seasoned Audi driver who has owned several models, I think this question deserves thorough discussion. Audi did have serious oil consumption issues in the past, especially with older turbocharged engines like the 2.0T - many owners complained about frighteningly fast oil consumption that required monthly top-ups. But the situation has improved significantly. Post-2017 models featuring third and fourth-generation EA888 engines adopted redesigned piston rings and better coatings, dramatically reducing oil consumption. My own 2020 Audi A6 has clocked 50,000 km with stable oil levels, rarely needing top-ups. However, no car should be taken for granted. I recommend regular dipstick checks, using full synthetic oil, and avoiding prolonged high-load operation like frequent high-speed runs or excessive short-trip cold starts. If you notice rapid oil level drops, promptly visit a professional shop to inspect valve seals or the PCV valve - better address minor issues before they become major repairs.
