How can I improve the fuel efficiency in my Ford S-Max?

I recently purchased a Ford S-Max and have noticed that I am filling up at the gas station more frequently than I expected. Is there anything I can do to improve the fuel efficiency of my car and save some money in the long run?

As a car enthusiast, I would recommend checking your tire pressure regularly. Underinflated tires can significantly decrease fuel efficiency.

Another suggestion would be to avoid using your air conditioning as much as possible. It can put extra strain on your engine and decrease fuel efficiency.

I have found that using cruise control on highway drives helps me maintain a steady speed and improves my fuel efficiency.
