What kind of oil should be added to an Audi A4?

[StEdward]

Audi A4 requires 5W-40 oil. Here are the detailed instructions: 1. The original factory oil used in Audi A4 complies with VW standard 502-00 and has a viscosity of SAE-5W-40. 2. Approximately 5L of oil is needed for maintenance replacement. If the maintenance is not performed at a 4S shop, it is necessary to pay attention to whether the oil used is of inferior quality. 3. The operation of the Audi A4 engine is highly efficient, with a high compression ratio that results in higher internal engine temperatures. Using oil with a higher viscosity value can protect the engine and cool the components to reduce the operating temperature. 4. The Audi A4 is equipped with a turbocharged engine. Compared to a naturally aspirated engine, its engine structure is more compact and the operating environment is more demanding, requiring higher-quality oil. It is advisable to use lubricants with better fluidity and preferably fully synthetic oil.
