How can I optimize my Nissan Qashqai's fuel efficiency?

I recently bought a Nissan Qashqai and noticed that it's not as fuel efficient as I expected. Is there anything I can do to improve its fuel efficiency?

One way to optimize your Nissan Qashqai's fuel efficiency is to make sure your tires are properly inflated. Under-inflated tires can decrease your car's fuel efficiency by up to 3%.

Another tip is to avoid aggressive driving, such as sudden accelerations and hard braking. This can lower your car's fuel efficiency by up to 40%.

Regular maintenance, such as oil changes and air filter replacements, can also help improve your car's fuel efficiency.
