What is the most efficient way to maintain my Audi engine's performance?

I recently bought a new Audi and I want to make sure I am properly maintaining the engine for top performance. What are the necessary steps for keeping my engine running smoothly?

Regular oil changes are crucial for keeping your Audi's engine running smoothly. It is recommended to change the oil every 7,500 miles or every 12 months, whichever comes first. This will help to prevent engine wear and improve performance.

In addition to regular oil changes, it is important to check and replace your air filter as needed. A clean air filter can improve engine performance and fuel efficiency.

Another important maintenance step is to check and replace spark plugs as needed. Old or worn out spark plugs can lead to poor engine performance and reduced fuel efficiency.
