How to maintain optimal performance in your Audi A5's engine?

I have recently noticed a decrease in the performance of my Audi A5's engine. What steps can I take to maintain its optimal performance?

Regular oil changes and engine tune-ups are essential to maintain the performance of your Audi A5's engine. I would recommend doing so at least twice a year.

In addition to regular maintenance, make sure to use high-quality fuel and keep your fuel tank at least half full to avoid buildup of sediment in the engine.

Another important factor is to drive your Audi A5 at least once a week, even if it's just for a short distance. This helps prevent the engine from staying inactive for prolonged periods of time.
