How do I improve the gas mileage of my Ford S-Max?

I just bought a Ford S-Max and I'm loving it, but I've noticed that my gas mileage is not as great as I had hoped. What are some ways that I can improve the gas mileage of my car?

You can try practicing better driving habits such as avoiding frequent braking and accelerating, making sure your tires are properly inflated, and using cruise control on the highway.

Another solution could be to get a tune-up for your car, as dirty air filters or spark plugs can decrease gas mileage.

Consider using a fuel additive or using a higher quality gasoline for better efficiency.
