What is the best way to improve gas mileage in my Nissan Micra?

I am looking for some tips to help improve the gas mileage on my Nissan Micra. I have been noticing it's been using more fuel than usual and I want to make sure I am doing everything I can to improve its efficiency. Any suggestions are greatly appreciated!

First, make sure your tires are properly inflated. Under-inflated tires can lead to decreased fuel efficiency.

Avoid aggressive driving and sudden stops. Smooth and steady driving can greatly improve gas mileage.
