How to increase gas mileage in BMW 5 Series?

I just bought a BMW 5 Series and I've noticed that the gas mileage is not as good as I expected. Is there anything I can do to improve it?

First, make sure your tires are properly inflated. Under-inflated tires can decrease your gas mileage. Second, avoid aggressive driving and excessive idling. This can waste unnecessary fuel. Lastly, consider getting your car's engine tuned and routine maintenance checks to improve overall efficiency.

One tip is to use cruise control on the highway to maintain a consistent speed and improve gas mileage. Also, try to plan your trips efficiently and combine multiple errands into one trip instead of making separate trips. This can help you save on gas and reduce emissions.

Avoid carrying unnecessary weight in your car, as this can decrease gas mileage. You can also try using premium fuel or fuel additives that claim to improve mileage, though results may vary. Lastly, consider changing your driving habits, such as accelerating slowly and avoiding sudden stops.
