How can I improve Ford Mondeo's fuel efficiency?

I recently purchased a Ford Mondeo and I've noticed its fuel consumption is quite high. I want to know what I can do to improve its fuel efficiency. Any tips or techniques that have worked for you in the past?

One effective way to improve fuel efficiency is to maintain proper tire pressure. This can make a significant impact on the amount of fuel your car consumes.

Avoid unnecessary idling and accelerate gradually instead of aggressively. This can also help conserve fuel.

Consider using cruise control while driving on highways as it can help maintain a consistent speed and conserve fuel.
