How to increase fuel efficiency on a Ford Mondeo?

I recently purchased a Ford Mondeo and was wondering if there is anything I can do to increase its fuel efficiency. I've heard of people using certain additives or changing their driving habits, but I'm not sure what actually works. Any suggestions?

While there are a few things you can do to improve fuel efficiency on your Ford Mondeo, the most effective method is by being mindful of your driving habits. Make sure to accelerate slowly and maintain a consistent speed on the highway. Also, try to avoid idling for long periods of time.

Another tip is to regularly check and replace your air filter. A clogged air filter can cause your engine to work harder and use more fuel. And don't forget to keep your tires properly inflated for better gas mileage.

I've also found that using a fuel system cleaner can help improve fuel efficiency. Just make sure to follow the instructions carefully and use a reputable brand.
