What kind of lubricant should I use for my Audi A6's engine?

I recently bought an Audi A6 and I'm planning on performing regular maintenance. I want to make sure I use the right kind of lubricant for my engine. What type of lubricant should I be using for my Audi A6's engine?

For your Audi A6's engine, it is recommended to use a synthetic oil with the viscosity grade of 5W-40, 0W-40 or 0W-30. These types of oil are specifically designed for high-performance engines, such as the one in your Audi A6.
