How can I improve the gas mileage in my Ford S-Max?

I just purchased a Ford S-Max and am disappointed with its gas mileage. What can I do to improve it?

The first step to improving your gas mileage is to make sure your tires are properly inflated. Underinflated tires can greatly decrease your fuel efficiency. Also, try to avoid idling for long periods of time and use cruise control on the highway to maintain a steady speed.

Consider changing your air filter and spark plugs if they are dirty. Dirty filters and plugs can cause your engine to work harder and use more gas. Also, try to limit the use of your air conditioning as it can significantly decrease your gas mileage.

Another tip for improving gas mileage is to plan your trips efficiently. When possible, try to combine multiple errands into one trip to reduce the amount of driving you do. And remember, driving at a steady pace and avoiding sudden accelerations and stops can also help save on gas.
