Which engine oil is recommended for an Audi A4?

I recently purchased a used Audi A4 and I am not sure which engine oil I should use. What type of engine oil is recommended for an Audi A4 and how often should it be changed?

The recommended engine oil for an Audi A4 is a synthetic 5W-30 oil. You should change the oil every 10,000 miles or every year, whichever comes first. This will help maintain the performance and longevity of your engine.

You should also make sure to use an engine oil that meets the Audi standard, which is API SN/CF or ACEA A3/B4. This will ensure your engine is well-protected and running smoothly.
