How do I maintain the best performance of my Audi's engine?

I recently bought a used Audi and I want to make sure I am taking good care of its engine. What steps should I follow to maintain its performance and extend its lifespan?

First, make sure to regularly change your engine oil according to the manufacturer's recommendations. This helps to keep the engine lubricated and clean.

Also, check and replace your air filter regularly to ensure proper air flow to the engine. This can improve fuel efficiency and overall performance.
