How many liters of engine oil should be added to the Volkswagen Tiguan L 2.0T?

[DiCorey]

Tiguan L 2.0T requires approximately 4 to 6 liters of engine oil. Below is relevant information about the functions of engine oil for vehicles: 1. Friction and high-temperature relief: A sufficiently thick oil film separates the surfaces of relatively sliding components, thereby reducing wear. 2. Sealing function: Engine oil can form a sealing ring between the piston rings and the piston, reducing gas leakage and preventing external contaminants from entering. 3. Anti-rust function: Lubricating oil adheres to component surfaces, preventing contact with water, air, acidic substances, and harmful gases. 4. Cushioning function: When the pressure in the engine cylinder rises sharply, suddenly increasing the load on the piston, piston skirt, connecting rod, and crankshaft bearings, this load is transmitted and lubricated through the bearings, cushioning the impact load. 5. Cleaning function: High-quality engine oil can carry carbon deposits, sludge, and worn metal particles from engine components into the oil tank through circulation, flushing away dirt generated on the working surfaces of the components via the flow of the lubricating oil.
