What is the best type of oil for an Audi A6?

I am considering changing the oil in my Audi A6 and I want to make sure I use the best type for optimal performance. Any recommendations?

For your Audi A6, I would recommend using a high-quality synthetic oil such as Mobil 1 or Castrol Edge. These oils are specifically designed for high-performance engines like the one in your Audi, and will help improve fuel efficiency and engine protection.

If you want to stick with a conventional oil, I would suggest using a 5W-30 or 0W-40 weight for your Audi A6. Look for brands that meet VW/Audi specifications such as Mobil Super or Pennzoil Platinum. These oils will provide good protection and performance for your engine.

Based on my experience with Audi A6s, I would recommend using a synthetic blend oil with a viscosity of 0W-40. This type of oil combines the benefits of both conventional and synthetic oils and is perfect for a high-performance engine like yours.
