How to increase the gas mileage of my Nissan Juke?

I have been noticing that my Nissan Juke's gas mileage has been decreasing lately. What could be the reasons for this and how can I improve its fuel efficiency?

Ensure that your tires are properly inflated to the recommended level by the manufacturer. Under-inflated tires can lead to increased fuel consumption.

Consider using a fuel additive that can help improve your car's fuel economy. Do some research and choose a trusted brand.

Make sure to get your car regularly serviced and maintain its engine in good condition. A well-maintained engine can significantly improve gas mileage.
