Is it necessary to regularly change the oil in an Audi A4?

I've heard conflicting opinions about how often the oil needs to be changed in my Audi A4. Some say every 5,000 miles, others say every 10,000. What's the best practice to ensure my car is running at its best?

Regular oil changes are essential to maintaining the performance and longevity of your Audi A4. It is recommended to change the oil every 5,000 miles, or every 6 months, whichever comes first. This will keep your engine running smoothly and prevent potential issues in the future.
