What is the best way to increase fuel efficiency in a Ford Mondeo?

I recently purchased a Ford Mondeo and have noticed that the fuel efficiency is not as good as I expected. What can I do to improve this?

One way to increase fuel efficiency is to regularly maintain your car. This includes regular oil changes and tire rotations.

Another tip is to avoid aggressive driving and try to maintain a steady speed while driving on the highway.

You can also try using a fuel system cleaner every few months to keep the engine running smoothly.
