What is the best way to improve the fuel efficiency of my Nissan Micra?

I have been struggling with high fuel costs and I want to find ways to improve the fuel efficiency of my Nissan Micra. I would appreciate any advice on how to achieve better mileage.

Regularly maintain your car by getting it serviced and replacing air filters for better fuel efficiency.

Drive at a steady pace and avoid sudden accelerations or braking to save fuel.

Check your tire pressure regularly as under-inflated tires can cause higher fuel consumption.
