How can I improve the fuel efficiency of my Nissan Micra?

I recently purchased a Nissan Micra and noticed that it doesn't get great gas mileage. Is there anything I can do to improve its fuel efficiency?

One easy way to improve the fuel efficiency of your Nissan Micra is to regularly change the air filter. A clogged air filter can decrease your gas mileage by up to 20%.

Another tip is to make sure your tires are properly inflated. This can help reduce friction and increase your fuel efficiency.
