How can I increase the gas mileage on my Nissan Micra?

I recently purchased a Nissan Micra and have noticed that it's not getting the same gas mileage as advertised. Is there anything I can do to improve its fuel efficiency?

Regular maintenance is key to improving gas mileage. Make sure to keep up with oil changes, tire pressure, and air filter replacements.

Consider getting a tune-up for your car. This can improve its overall performance and potentially increase gas mileage.
