How do you improve fuel efficiency in a Nissan Micra?

I've just bought a used Nissan Micra and I'm worried about its fuel efficiency. How can I improve it?

First of all, make sure to regularly maintain your vehicle. This includes things like changing the oil and air filter, checking tire pressure, and getting tune-ups. These simple tasks can greatly improve your fuel efficiency.

Another tip is to avoid aggressive driving. This means avoiding sudden accelerations and braking, as they use up more fuel. Try to maintain a steady speed and use cruise control when possible.
