How to improve fuel efficiency in Nissan Micra?

My Nissan Micra seems to be consuming a lot of fuel lately. How can I improve its fuel efficiency?

Make sure to regularly check and replace your air filters. Clogged air filters can significantly reduce fuel efficiency.

Avoid aggressive driving and maintain a constant speed. Rapid acceleration and braking can increase fuel consumption.

Consider using premium or high-grade fuel, as it can provide better mileage and performance.
