Not all Audi S4s are the same because they have different engines across different model years. Here are some general tips for these cars: It's usually better to opt for synthetic oil rather than conventional, although a blend is also an option. Synthetic oil tends to perform better for these engines in terms of performance. Typically, the factory recommends using SAE 5W-40 oil, which is usually the best choice. However, in certain situations, you can use 5W-30 oil as an alternative. Depending on the climate you're driving in, you may even consider using a range from 0W-30 to 10W-40 oil.
Your Audi S4 car is designed to run on 5W-40 synthetic oil in its engine.
