What type of engine oil does the Audi A6 require?

Can someone provide information on the recommended engine oil for the Audi A6 and any specific grades or brands that are compatible? Please provide a detailed explanation.

According to the Audi A6 owner's manual, the recommended engine oil is fully synthetic 0W-40. Given the high performance of the Audi A6, it is important to use a high-quality oil to prolong the engine's life and maintain optimal performance. Some compatible brands include Mobil 1, Castrol, and Pennzoil.

I always use fully synthetic 0W-40 oil for my Audi A6 and have had great results. I highly recommend sticking to this grade and using a reputable brand, such as AMSOIL or Royal Purple. Regular oil changes are key to keeping your Audi's engine running smoothly.

I recently spoke to a mechanic who specializes in Audi vehicles and they recommended using fully synthetic 0W-40 oil for the Audi A6. They advised against using blends or lower grade oils as it can affect the engine's performance and potentially cause issues.
