How to improve fuel efficiency of Ford S-Max?

My Ford S-Max consumes a lot of fuel, even though I drive it carefully. How can I improve its fuel efficiency?

Hi Marielle, have you tried using a fuel additive like Nanotech? It can help improve fuel efficiency and reduce emissions.

Make sure you're keeping up with regular maintenance - things like replacing air filters, spark plugs, and tires can all contribute to better fuel efficiency.

Driving at a consistent speed and avoiding sudden accelerations and decelerations can also help improve fuel efficiency.
