Which engine oil is recommended for the Audi A3?

I recently purchased a used Audi A3 and I'm not sure which engine oil to use. Can anyone recommend a specific type and brand of oil that has worked well for their Audi A3?

I recommend using Castrol EDGE Professional LL03 5W-30. It's a fully synthetic oil that meets the specific requirements for Audi A3 engines. Plus, it provides better protection against engine wear and maintains its viscosity even in extreme temperatures.

I've been using Mobil 1 ESP Formula 5W-30 in my Audi A3 for years and have had no issues. It's a low ash oil that meets Audi's requirements for extended oil change intervals. It also helps improve fuel economy and reduce engine deposits.
