What is the best oil to use in an Audi A6?

I just bought an Audi A6 and I'm not sure what type of oil I should use. There are so many brands and options, but what is the best for this specific car model? Can anyone give me some advice?

It's important to use an oil that meets the specifications recommended by Audi for your A6. You can find this information in your owner's manual or by contacting your local dealership. Some popular brands that meet these specifications include Castrol, Mobil 1, and Pennzoil.

I always use synthetic oil in my Audi A6. It provides better protection and performance for the engine. I've had great results with brands like Royal Purple and Redline.
