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

I recently purchased a Ford S-Max and I love everything about it, except the fuel efficiency. Is there anything I can do to improve it?

As a car enthusiast, I highly recommend using a fuel system cleaner every 3,000 miles. It helps improve fuel efficiency and overall engine performance.

Switching to premium unleaded fuel can also make a noticeable difference in fuel efficiency for the S-Max. Though it may cost a bit more upfront, it can save you money in the long run.

Avoid excessive idling and aggressive driving to maximize fuel efficiency. Also, make sure your tires are properly inflated for optimal performance.
