How can I improve my Nissan Juke's fuel efficiency?

I recently purchased a Nissan Juke and noticed that it's not getting great gas mileage. What can I do to improve its fuel efficiency?

One thing you can do is regularly check and replace your air filter. A dirty filter can reduce your fuel efficiency.

Try avoiding excessive idling and using your cruise control on the highway. These habits can help improve your gas mileage.
