What is the most efficient way to maintain the optimal engine performance of an Audi A5?

I have recently purchased a brand new Audi A5 and want to ensure that the engine performs at its best for years to come. What steps can I take to maintain the optimal performance of the engine, while also ensuring its longevity?

Regularly change the engine oil and filter, as this helps to remove impurities and keeps the engine running smoothly. Additionally, using high-quality synthetic oil can also improve engine performance and longevity.
