How to maintain the engine in my Audi A4?

I recently purchased an Audi A4 and I want to make sure I am properly maintaining the engine. What are some important things I should know?

Regular oil changes are crucial for keeping your engine running smoothly and preventing damage. It's recommended to change the oil every 5,000 to 7,500 miles or every 6 months.

Make sure to check your coolant level regularly and top it off if needed. Low coolant can lead to overheating and potential engine damage.

Be mindful of the fuel you use in your Audi A4. Using premium fuel with a higher octane rating can help maintain your engine's performance and efficiency.
