The Audi A6 requires premium unleaded fuel with a minimum octane rating of 91. Using a lower octane fuel can result in engine knocking and decrease performance.

In addition to using the recommended fuel, regularly servicing your car, including changing the fuel filter, can help maintain the car's performance.

If the recommended fuel is not available, using a higher octane fuel is acceptable. However, using a lower octane fuel can cause issues with the engine and decrease fuel efficiency.
