How do I properly maintain the engine of my Audi car?

I recently purchased an Audi car and I want to make sure I am properly maintaining the engine. What specific steps should I take to ensure the longevity of my engine and avoid any potential issues?

Regular oil changes are essential for maintaining the performance of your Audi's engine. Make sure to adhere to the recommended schedule based on your specific model and driving habits.

In addition to regular oil changes, it's important to also check and replace the air filter and spark plugs as needed. These components affect the overall health of your engine and should not be neglected.
