How do I maintain my Ford S-Max's fuel efficiency?

I recently bought a Ford S-Max and I'm wondering how I can ensure that I am getting the best fuel efficiency out of it. Are there any specific maintenance tasks or driving habits that I should be aware of?

First of all, make sure to keep up with regular maintenance tasks such as oil changes and tire rotations. Additionally, try to avoid aggressive driving and unnecessary idling to save on gas.

Another tip is to keep your car's weight as light as possible, so avoid carrying unnecessary items or roof racks if you are not using them. This can help improve your fuel efficiency.
