Can I use regular unleaded gas in my Audi A7?

I recently bought a pre-owned Audi A7 and I was wondering if it's okay to use regular unleaded gas instead of premium? I heard it could save me some money but I don't want to damage my car's engine.

Yes, you can use regular unleaded gas in your Audi A7. However, keep in mind that your car's engine was designed to run on premium gas, so using regular gas may affect its performance and fuel efficiency. It's best to stick with the recommended premium gas for optimal performance.

Using regular unleaded gas once in a while won't harm your engine, but it's not recommended for long-term use. Regular gas has a lower octane rating than premium, which could potentially cause knocking and decrease your car's overall performance.
