What is the best brand of oil for an Audi A8?

I just bought an Audi A8 and I'm wondering what brand of oil is best for it. I want to make sure I'm using the right one for optimal performance.

I've personally had great results with Castrol EDGE synthetic oil in my Audi A8. It provides excellent engine protection and can handle extreme driving conditions.

I would recommend sticking with the brand recommended by Audi, as they have tested and approved it for your specific vehicle. It's important to use the right type and grade of oil to avoid any potential engine problems.

I always use Mobil 1 synthetic oil in my Audi A8 and have never had any issues. It's a bit more expensive, but I feel that the extra protection and quality are worth it in the long run.
