Do Volkswagen cars still burn oil now?
1 Answers
Volkswagen cars are designed to protect the engine and extend its lifespan by reducing the frictional resistance between the piston rings and the cylinder walls. An oil film forms on the cylinder walls, and part of this oil film is burned off with the high-temperature combustion gases, resulting in higher oil consumption compared to other vehicles. The reasons why Volkswagen cars burn oil: 1. The oil separator often fails, leading to ineffective oil vapor and water separation. Additionally, the plastic strength of the camshaft end cover is insufficient, causing poor sealing between the end cover and the engine block, which results in oil leakage. 2. There is also a design flaw in the pressure valve below the separator, which allows oil to leak. 3. In turbocharged models, oil is required for cooling, and some of this oil evaporates while cooling the turbocharger.
