What type of fuel should I use for my Audi A8?

I just bought an Audi A8 and I'm not sure what type of fuel I should use. Can I use regular unleaded gasoline or do I need to use a premium fuel? Will using a lower grade fuel affect the car's performance or reliability? Please advise.

As a general rule of thumb, it is recommended that you use premium fuel for your Audi A8. This is because premium fuel has a higher octane rating, which means it can handle higher levels of compression without causing problems. Using a lower grade fuel may affect the car's performance and fuel economy, as well as potentially damaging the engine in the long run.

You can technically use regular unleaded gasoline in your Audi A8, but it is not the recommended fuel. Premium fuel will provide better performance and fuel efficiency, which is important for a luxury car like the Audi A8. Although it may be slightly more expensive, the extra cost is worth it in the long run.
