How do I know if my Audi A4 needs an oil change?

I recently purchased an Audi A4 and I'm not sure how often I need to change the oil. Can anyone give me some advice on how to tell if my car needs an oil change and how often I should do it?

As a general rule, it is recommended to change your oil every 5,000 to 7,500 miles. However, this may vary depending on your driving habits and the type of oil you use. To be safe, it's best to check your owner's manual for specific recommendations for your model.

You can also check the oil level and color yourself. When the oil level is low and the oil color is dark and dirty, it's time for an oil change. It's a good idea to check this every month or so, especially if you do a lot of driving.
