Can I use regular gasoline in my BMW M3?

I've heard that high-performance cars like the BMW M3 require high-octane gasoline. Is it safe to use regular gasoline in my M3?

As a general rule, it's always best to follow the manufacturer's recommendation for fuel type. In this case, BMW recommends using premium gasoline in your M3. Using regular gasoline may lead to engine knocking and lower overall performance. However, in a pinch, you can use regular gasoline as long as it meets the minimum octane rating of 91. Just remember that this may affect your car's performance and fuel economy.
