Should I use synthetic or conventional oil in my Audi A4?

As a new Audi A4 owner, I'm not sure which type of oil is best for my car. Are there any advantages or disadvantages to using synthetic or conventional oil? And how often should I change the oil?

Synthetic oil is generally considered to be better for high-performance engines like those found in Audi vehicles. It provides better protection, lasts longer, and performs better in extreme temperatures. However, it is more expensive than conventional oil. As for how often you should change the oil, it is recommended to follow the manufacturer's guidelines, typically every 5,000-10,000 miles.
