Why does my Ford S-Max have poor fuel efficiency?

I recently bought a Ford S-Max and I noticed that it's consuming more fuel than my previous car. What could be causing this and what can I do to improve its fuel efficiency? Thanks.

Hi John, there could be several reasons for poor fuel efficiency in your Ford S-Max. It could be due to a clogged air filter, spark plugs, or even your driving habits. I suggest checking and replacing any damaged or dirty components and trying to drive more efficiently.

Hey John, have you tried using a fuel additive for your Ford S-Max? It can help clean out any deposits in the fuel system and improve fuel economy. Also, make sure to keep your tires properly inflated and avoid any unnecessary idling.

Hi John, another factor that can affect fuel efficiency is the type of oil used in your car. Make sure to use the recommended grade of oil for your Ford S-Max and change it regularly. This can also help improve your car's overall performance.
