Why is the gas mileage on my Nissan Qashqai lower than expected?

I recently purchased a Nissan Qashqai and I've noticed that the gas mileage doesn't seem to be as good as advertised. What could be causing this issue and what steps can I take to improve the efficiency of my vehicle?

There could be several factors that are contributing to the lower gas mileage on your Nissan Qashqai. First, make sure that your tires are properly inflated and that you're not carrying any unnecessary weight in your vehicle. It's also important to avoid aggressive driving and to keep up with regular maintenance, such as oil changes and air filter replacements.

Weather can also play a role in your vehicle's gas mileage. Cold temperatures can cause your engine to work harder and use more fuel. If you live in a colder climate, consider using a block heater or parking in a garage to help improve your gas mileage.
