Best way to improve the fuel efficiency of a Ford S-Max?

I recently purchased a Ford S-Max and I'm looking for ways to improve its fuel efficiency. I've heard about different techniques such as hypermiling and using a fuel economy chip. Which methods have worked best for you?

I've found that maintaining a consistent speed and avoiding sudden accelerations can greatly improve fuel efficiency. Also, keeping your tires properly inflated and using synthetic oil can help.

I've had success with using a fuel economy chip. It optimizes the engine's performance and can give you better mileage. Just make sure to do your research and purchase a reputable chip.

Hypermiling techniques, such as coasting and drafting behind larger vehicles, can definitely make a difference in fuel efficiency. However, they may not be practical for everyday driving.
