How to get the best fuel efficiency in a Nissan Micra?

My Nissan Micra seems to be using a lot of fuel lately. I'm wondering if there are any tips or tricks to help improve the fuel efficiency?

First, make sure to keep up with regular maintenance such as oil changes and tire rotations. This can greatly improve fuel efficiency.

Avoid aggressive driving, such as quick accelerating and braking, as it can use up more fuel. Try to maintain a steady speed.

Check your tire pressure regularly. Low tire pressure can cause your car to use more fuel.
