How do I improve the fuel efficiency in my Ford Mondeo?

My Ford Mondeo seems to use a lot of gas, what can I do to improve its fuel efficiency?

First, make sure you are using the recommended fuel octane for your car. Also, regularly check and replace the air filter, and maintain proper tire pressure. These small maintenance tasks can greatly improve fuel efficiency.

I highly recommend getting your car tuned up by a professional at least once a year. They can optimize the car's performance and make sure all the parts are running efficiently.

You can also try driving at a slower speed and avoiding quick accelerations and stops. This can save a lot of gas in the long run.
