How much engine oil should be added to an Audi A4L?

[StTimothy]

Audi A4L requires 4.5 liters of engine oil. The following are the related introductions about Audi A4L engine oil: 1. Reduce wear: There is rapid relative sliding between the piston and cylinder, as well as between the main shaft and bearing. To prevent excessive wear of parts, it is necessary to establish an oil film of sufficient thickness between the two sliding surfaces to separate the relatively sliding parts and reduce wear, thereby extending the mechanical lifespan. 2. Cooling: Engine oil can help the radiator cool the engine and expel heat from the engine. 3. Sealing and leakage prevention: Engine oil can form a sealing ring between the piston ring and the piston, reducing gas leakage and the entry of pollutants.
