How do I make my Nissan Qashqai run more efficiently?

I have a 2015 Nissan Qashqai and I feel like it's not running as efficiently as it used to. Is there anything I can do to improve its performance and save on gas?

Regularly maintaining your Nissan Qashqai can significantly improve its performance and efficiency. Make sure to check and change your air filter, spark plugs, and oil regularly.

Consider upgrading to a more efficient engine oil with a lower viscosity grade. This can reduce friction and improve your car's fuel economy.

Another tip for improving efficiency is to avoid quick acceleration and heavy braking. This can put unnecessary strain on your engine and decrease fuel efficiency.
