How can I improve the fuel economy on my BMW 8 Series?

I recently purchased a BMW 8 Series and although I love the car, I am concerned about its fuel efficiency. Are there any steps I can take to improve the fuel economy?

First and foremost, make sure your tires are properly inflated. Under-inflated tires can significantly decrease your fuel efficiency. Additionally, try to merge smoothly and avoid sudden bursts of acceleration.

Using cruise control while on the highway can also help improve your fuel economy. This allows the car to maintain a consistent speed, using less fuel in the process.

Another tip for improving fuel efficiency is to reduce your car's weight. Remove any unnecessary items from your car, as the added weight can increase fuel consumption.
