How do I maintain my Audi A6's engine for optimal performance?

I have recently purchased an Audi A6 and I want to make sure that I am properly maintaining the engine to ensure it runs smoothly and efficiently. What are some key maintenance tasks I should be aware of and how often should I perform them? Thank you in advance for your advice!

Regular oil changes are crucial for keeping your Audi A6's engine running at its best. Make sure to follow the manufacturer's recommended schedule, typically every 5,000 to 7,500 miles.

Additionally, it's important to keep an eye on your coolant levels and regularly replace your coolant every 2-3 years. This will prevent your engine from overheating and causing any potential damage.
