What is the best motor oil for an Audi A6?

I just bought an Audi A6 and I want to make sure I am using the best motor oil for my car. What type of motor oil should I be using and how often should I change it? Thanks in advance for your help!

For optimal performance, it is recommended to use a high-quality synthetic motor oil with a viscosity of 5W-30 or 0W-40. As for how often to change it, Audi recommends every 10,000 miles or 1 year, whichever comes first.

I've been using Castrol EDGE in my Audi A6 for years and I haven't had any issues. It's a premium synthetic oil with a 5W-30 viscosity and it meets Audi's specifications. I change it every 8,000 miles to be safe.

I would advise against using conventional motor oil in your Audi A6 as it may not provide the necessary protection and performance. Stick with a high-quality synthetic oil and follow the manufacturer's recommended intervals for oil changes. You can also refer to your car's owner's manual for specific recommendations.
