What is the most efficient way to improve the fuel economy of my Ford S-Max?

I have been driving my Ford S-Max for a few months now and I've noticed that it's not as fuel efficient as I expected. I want to improve its fuel economy but I'm not sure how. Any tips or tricks?

One tip is to make sure you are using the correct tire pressure for your Ford S-Max. Underinflated tires can decrease your fuel efficiency.

Another way to improve fuel economy is to avoid excessive idling and driving at high speeds. Both of these can greatly impact your gas mileage.

Regular maintenance, such as oil changes and air filter replacements, can also greatly improve the fuel efficiency of your Ford S-Max. Make sure you're following the recommended schedule.
