Why do I need to use premium fuel in my Audi A4?

I recently purchased an Audi A4 and noticed that the manufacturer recommends using premium fuel. But why is this necessary and what are the potential consequences of using lower octane fuel?

Premium fuel is necessary for your Audi A4 because it has a high compression engine. Using regular fuel could result in engine knocking, decreased performance, and potential damage to your engine.

Using premium fuel ensures that your Audi A4 operates at its optimum level. Lower octane fuel may save you a few dollars at the pump, but it can lead to decreased fuel efficiency and potential engine issues down the road.

As someone who has owned multiple Audis, I highly recommend sticking to premium fuel. It's a small investment for the longevity and performance of your vehicle.
