What is the most efficient way to maintain the fuel efficiency of a Ford S-Max?

I have recently purchased a Ford S-Max and I am looking for ways to keep its fuel efficiency at its peak. Can you suggest some tips or techniques?

The most efficient way to maintain the fuel efficiency of your Ford S-Max is to regularly check and replace the air filter.

Another important aspect to consider is regular tire maintenance. Properly inflated tires can greatly improve fuel efficiency.

Avoid excessive idling and unnecessary weight in the car. These can both negatively impact fuel efficiency.
