How do I know when it's time to change the oil in my Audi A3?

I recently bought an Audi A3 and I'm not sure how often I need to change the oil. Can anyone tell me the mileage or time interval for oil changes on this car?

The recommended interval for oil changes on the Audi A3 is every 10,000 miles or every year, whichever comes first. However, if you drive predominantly in city or stop-and-go traffic, it's best to change the oil every 5,000 miles or every six months.

You can also check your car's owner's manual for the recommended oil change interval specific to your model of Audi A3. If you're unsure or have any questions, it's always a good idea to consult with a certified mechanic.
