Which engine oil should I use for my Audi A6?

I recently purchased an Audi A6 and I am wondering what type of engine oil I should use for optimal performance and longevity. I want to make sure I am using the correct oil for my specific model and engine type.

For your Audi A6, it is important to use a synthetic oil with a viscosity of 5W-30. This ensures that your engine is properly lubricated and protected from wear and tear. As for brand, it is recommended to stick with high-quality, reputable brands such as Mobil 1 or Castrol.
