What is the best oil type for my Audi A4?

I recently purchased a used Audi A4 and I want to make sure I am using the right type of oil for my car. What type of oil is recommended for an Audi A4 and how often should I change it?

The best oil type for your Audi A4 is 5W30 full synthetic. This type of oil provides better engine protection and performance, especially during cold weather. As for the oil change frequency, it is recommended to change it every 5,000 miles or every 6 months.

I would highly suggest using 5W40 full synthetic oil for your Audi A4. It is designed specifically for high-performance engines like the one found in your Audi. As for frequency, it's best to follow the manufacturer's recommendation of changing it every 10,000 miles or every 12 months.
