How to make my Nissan Qashqai more fuel efficient?

I recently bought a Nissan Qashqai and I love it, but I find myself spending a lot on gas. Is there any way to improve its fuel efficiency without sacrificing performance?

One way to improve fuel efficiency is to regularly maintain your car. Make sure to get your oil changed, replace air filters, and keep your tires properly inflated. This can greatly improve your car's performance.
