What is the best way to maintain good fuel efficiency in a Nissan Micra?

I just bought a Nissan Micra and I'm looking for advice on how to maintain good fuel efficiency. I want to make sure I get the best MPG possible. Any tips or tricks would be greatly appreciated!

Regularly check and maintain your tire pressure. Under-inflated tires can decrease fuel efficiency.

Avoid excessive idling and unnecessary acceleration. Both can waste fuel.

Plan your trips efficiently to avoid unnecessary mileage.
