Regularly scheduled maintenance is crucial for keeping your Audi A6 engine running smoothly. Make sure to follow the manufacturer's recommended service intervals and keep up with oil changes.

In addition to regular maintenance, using high-quality fuel and additives can also help to improve engine performance. Consider using fuel additives specifically designed for Audi engines.
