Which oil is best for an Audi A6?

I just got an Audi A6 and I want to know which type of oil is recommended for it. I've heard conflicting information and I want to make sure I'm using the right one.

For your Audi A6, it is recommended to use a synthetic oil with a weight of 0W-40. This will provide the best protection for your engine.

I've been using Castrol EDGE 5W-30 in my Audi A6 and I haven't had any issues. It's important to follow the manufacturer's recommendations and make sure the oil meets the required specifications.

Based on my experience, I would suggest using Mobil 1 0W-40. It's a high-quality synthetic oil that has worked well in my Audi A6 for years.
