How to maintain optimal engine performance in Audi A6?

I have noticed a decrease in my Audi A6's engine performance lately. How can I ensure that it stays at its optimal level?

Regular engine maintenance is key. Make sure to keep up with oil changes and replace air filters as recommended by your car manual. Also, consider using high-quality fuel and additives to keep your engine running smoothly.

Check for any engine error codes and address them promptly. Don't ignore any warning lights on your dashboard. It could be a simple fix or a sign of a larger issue. It's best to get it checked by a professional.

Don't push your engine too hard. Audi A6 is a powerful car, but it's important to let it warm up properly before driving and not rev the engine excessively.
