How to improve the fuel efficiency on my Nissan Micra?

I recently purchased a new Nissan Micra and noticed that I am spending a lot on fuel. Any suggestions on how to improve its fuel efficiency without sacrificing performance?

Regularly maintain your car by keeping up with oil changes and tire pressure to ensure it is running at its best. This can greatly improve fuel efficiency.

Avoid idling for long periods of time and turn off the engine when parked. This can help decrease fuel consumption and save you money.
