One great way to improve your Nissan Qashqai's fuel efficiency is by making sure your tires are properly inflated. This can greatly improve the gas mileage of your vehicle.

Another tip is to avoid idling for long periods of time. If you know you'll be stationary for more than a minute, it's better to turn off your engine and save gas.
