What is the recommended octane rating for the Audi 80?

I just purchased an Audi 80 and I'm unsure of what octane rating fuel I should be using. I want to ensure my car is running efficiently and not causing any damage.

The recommended octane rating for the Audi 80 is 91 or higher. Using a lower octane fuel can cause engine knocking and potentially damage your car's performance. Stick to the higher octane options for optimal efficiency and to avoid any potential issues.

While the Audi 80 can technically run on a lower octane fuel, it is not recommended. In the long run, using a lower octane fuel can lead to engine issues and costly repairs. Stick to the manufacturer's recommendation and use a higher octane rating for optimal performance.

I've been driving an Audi 80 for years and have always used a higher octane fuel. I've never had any issues and have noticed a significant improvement in performance and fuel efficiency. I highly recommend sticking to the manufacturer's recommended octane rating.
