What is the best engine oil for a Audi A6?

I just got a new Audi A6 and want to make sure I am using the best engine oil to maintain its performance. What type of engine oil should I use and at what intervals should I change it? Any recommendations would be greatly appreciated.

For an Audi A6, it is recommended to use a fully synthetic engine oil with a viscosity of 5W-30. You should change the engine oil every 10,000 miles or once a year, whichever comes first. This will ensure optimal performance and longevity for your car.
