How to maintain the engine of my Nissan Qashqai?

I've noticed my Nissan Qashqai's engine is not performing as well as it used to. What steps should I take to maintain it?

Regularly check and change the oil and oil filter to ensure proper lubrication and prevent engine damage.

Keep an eye on the cooling system and make sure there are no leaks or malfunctions. Low coolant levels can cause the engine to overheat.

Pay attention to warning lights and get your car serviced as soon as possible to avoid any potential engine issues.
