Can I use regular gas in a BMW 5 Series?

I just bought a BMW 5 Series and I'm wondering if I can save some money by using regular gas instead of premium. Will it harm my car's engine?

It is not recommended to use regular gas in a BMW 5 Series as it can affect the performance and longevity of the engine. Premium gas is designed to provide the necessary octane level for the engine to run efficiently. Using regular gas can lead to engine knocking and potentially damage the engine over time.
