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

I recently bought a Ford S-Max and am looking for ways to improve its gas mileage. Any suggestions?

I've had good luck using a fuel system cleaner every few thousand miles. It helps keep the engine running efficiently and can improve gas mileage.

Check your tire pressure regularly, as low tire pressure can decrease gas mileage.

Consider getting a tune-up for your Ford S-Max, as a properly tuned engine can improve gas mileage.
