What Causes Volkswagen to Burn Engine Oil?
1 Answers
Volkswagen burning engine oil can be attributed to the following reasons: 1. Low-quality engine oil or incorrect viscosity grade: Using low-grade oil can exacerbate wear. If the oil viscosity is either too low or too high, it can lead to inadequate engine lubrication, increasing wear on piston rings and cylinder walls, reducing sealing performance, and causing oil to burn. 2. Overfilling of engine oil: When the oil level exceeds the centerline, the high oil pressure can cause excessive oil to enter the combustion chamber during the engine's splash lubrication process, leading to excessive burning. 3. Turbocharger oil leakage: The turbocharger's turbine shaft is supported by lubricated floating bearings. Vehicles equipped with turbochargers have an oil passage leading to the turbocharger. Leakage in the oil line or bearings can allow oil to seep from the turbocharger into the exhaust pipe. When the exhaust pipe temperature is high, the oil is baked and emitted as blue smoke.
