How do I maintain my Audi's engine performance?

I have an Audi A5 and I'm noticing a decrease in its engine performance. How often should I change the oil and what type of oil should I use to ensure the best performance?

Regular oil changes are crucial for maintaining the performance of your Audi's engine. As a general rule, you should aim to change the oil every 5,000 to 7,500 miles. When it comes to choosing the right oil, make sure to use a high-quality, synthetic oil that meets the specifications outlined in your owner's manual. This will help keep your engine running smoothly and protect against wear and tear.
