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

I have recently purchased an Audi and I want to make sure that I am taking all the necessary steps to maintain its engine's performance. I have heard different opinions about how often I should change my oil or what type of fuel is best for my car. I am looking for a definitive answer from expert car enthusiasts.

Regular oil changes are crucial for maintaining your Audi's engine performance. It is recommended to do so every 5,000 to 7,500 miles depending on your driving habits and the type of oil used. Stick to high quality synthetic oils for optimal performance.
