What type of fuel does the Audi A4 require?

I recently purchased a new Audi A4 and I am unsure of which type of fuel to use. Can anyone provide recommendations on the type of fuel that is best suited for the Audi A4?

The Audi A4 is designed to run on premium unleaded gasoline with a minimum octane rating of 91. This type of fuel will provide optimal performance and keep your engine running smoothly. As a general rule, it is best to stick with the recommended fuel type for your vehicle.

While the Audi A4 can technically run on regular octane fuel, it is highly recommended to use premium unleaded gasoline for the best results. Not only will this ensure proper engine function, but it can also help improve fuel efficiency and save you money in the long run.

I have been using regular fuel in my Audi A4 for years and have not noticed any issues. However, I recently switched to premium fuel and have noticed a significant improvement in both performance and fuel economy. I highly recommend using premium fuel for your Audi A4.
