How to improve the gas mileage of my Ford S-Max?

I recently purchased a Ford S-Max and I've noticed that the gas mileage is not as good as I expected. What can I do to improve it?

Firstly, make sure your tires are properly inflated. Under-inflated tires can decrease gas mileage. You can also consider getting fuel-efficient tires.

Avoid aggressive driving and excessive idling as they can also decrease gas mileage. It's better to accelerate slowly and smoothly while driving.

Regular maintenance, like oil changes and air filter replacements, can also improve gas mileage. Make sure to follow your vehicle's recommended maintenance schedule.
