Volkswagen Passat excessive oil consumption requiring frequent oil changes on Volkswagen Passat

Some Volkswagen Passat owners report experiencing excessive oil consumption, which may necessitate frequent oil changes. Common causes include worn-out valve seals, piston rings, and gaskets that can lead to oil leakage or burning, resulting in higher consumption rates. If the engine consumes more than 1 liter of oil per 10,000 kilometers, it indicates a problem that requires prompt attention. Additionally, leaking rings in the engine can allow oil to escape, further increasing consumption and decreasing performance. Neglecting routine oil changes and not adhering to the recommended maintenance schedule can also contribute to oil degradation and excessive consumption. Addressing these issues through regular maintenance and timely repairs is crucial for maintaining optimal engine performance and reducing the frequency of oil changes.
