What is the best oil to use for an Audi engine?

I recently purchased an Audi and want to make sure I'm using the best type of oil for my car's engine. I've heard different opinions and want to know the definitive answer.

The best oil to use for your Audi engine is a fully synthetic oil, specifically one that meets the VW 502.00 or 504.00 standards.

I use Castrol Edge 5W-40 in my Audi and have had great results. It's important to make sure you choose an oil that meets the manufacturer's specifications.

I work at an Audi dealership and can tell you that the recommended oil for your car is Mobil 1 ESP 0W-40. It's specifically formulated for Audi engines and provides excellent protection.
