How to increase fuel efficiency in my Ford Mondeo?

I have noticed that my Ford Mondeo has been consuming more fuel than usual. Is there any way I can increase its fuel efficiency?

One way to increase fuel efficiency in your Ford Mondeo is to regularly maintain and replace worn out spark plugs and air filters. This will improve the engine's combustion, leading to better fuel efficiency.

Keeping your tires properly inflated can also improve your Ford Mondeo's fuel efficiency. Underinflated tires create more resistance, thus using more fuel.

Another tip is to avoid idling your car for too long. Turn off the engine if you're going to be stationary for more than a minute.
