How do I increase the fuel efficiency of my BMW M5?

I recently purchased a BMW M5 and I love its performance, but I'm concerned about its fuel efficiency. Is there anything I can do to improve it?

First, make sure that your tires are properly inflated and that you are using the recommended fuel for your BMW M5. You can also try switching to a higher octane fuel to see if that improves your fuel efficiency. Additionally, make sure to avoid unnecessary idling and use your cruise control when driving on the highway.

Another important factor is your driving habits. Aggressive driving, such as quick acceleration and braking, can greatly decrease your fuel efficiency. Try to maintain a steady speed and use your brakes and accelerator smoothly.
