How do I improve fuel efficiency on my Ford Mondeo?

I recently bought a Ford Mondeo and I noticed that I'm spending a lot on gas. What are some tips or modifications I can make to improve fuel efficiency?

One way to improve fuel efficiency on your Ford Mondeo is to regularly maintain your car. Make sure to change the oil and air filter as recommended by the manufacturer. This can greatly improve your fuel consumption.

Another tip is to avoid aggressive driving. This includes hard braking and accelerating as it can greatly affect your fuel consumption. Try to maintain a steady speed and use cruise control whenever possible.
