Why is my Nissan Qashqai's fuel economy not as good as expected?

I recently bought a Nissan Qashqai and was told it had great fuel economy. However, I have noticed that it's not living up to its reputation. What could be causing this and what can I do to improve it?

There could be several reasons for your Nissan Qashqai's lower than expected fuel economy. One possibility is that you may be using a lower grade fuel than what is recommended for your specific model. Another possibility is that your tires may not be properly inflated, which can greatly affect fuel efficiency. You may also want to consider having your car's air filters and spark plugs checked, as these can also impact fuel economy. I would recommend bringing your car to a trusted mechanic for a thorough check-up and to also discuss any potential driving habits that could be contributing to the issue.
