What is the recommended octane rating for a 1999 Audi 80?

I recently purchased a 1999 Audi 80 and I was wondering what the optimal octane rating for the fuel is. I want to make sure I am using the right type of fuel for my car.

The recommended octane rating for a 1999 Audi 80 is 91 AKI (95 RON). This will ensure your car runs smoothly and efficiently.

Using a lower octane fuel in a high-performance car like the 1999 Audi 80 can lead to engine knocking and decreased fuel economy. Stick with the recommended 91 AKI for best results.
