How can I improve my car's gas mileage?

I recently bought a Nissan Micra and I feel like I'm spending a lot on gas. Is there anything I can do to improve my car's gas mileage?

There are a few things you can do to improve your car's gas mileage. First, make sure your tires are properly inflated. Under-inflated tires can decrease your gas mileage. Additionally, try to avoid idling for long periods of time and use cruise control while driving on the highway.
