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

I recently purchased a Ford S-Max and have noticed that the fuel efficiency isn't what I expected. Are there any specific techniques or modifications I can make to improve the fuel efficiency of my car?

One way to increase your Ford S-Max's fuel efficiency is to make sure to keep up with regular maintenance and tune-ups. This includes keeping your tires properly inflated and using the recommended motor oil for your car.

Another tip is to avoid accelerating quickly and braking hard, as this uses more fuel. Instead, try to maintain a steady speed while driving and anticipate traffic flow to avoid sudden stops and starts.

You may also want to consider investing in aerodynamic accessories for your car, such as a spoiler or air deflector, to reduce drag and improve fuel efficiency.
