What is the best way to maintain the engine of an Audi A6?

I have recently purchased a used Audi A6 and want to make sure I am properly maintaining its engine to ensure optimal performance and longevity. What are the recommended maintenance tasks and intervals for an Audi A6 engine?

To maintain the engine of your Audi A6, make sure to regularly change the oil every 5,000 miles or 6 months and replace the air filter every 20,000 miles or 2 years.

Additionally, check your spark plugs every 30,000 miles and replace them if necessary. This will ensure your engine is running efficiently and prevent any potential issues.

It is also important to follow the manufacturer's recommendations for timing belt replacement. This will prevent costly damage to the engine in the long run.
