What are some tips for maintaining my Nissan X-Trail's engine?

My Nissan X-Trail has been giving me some issues lately and I want to make sure that my engine stays in good condition. Are there any tips or preventive measures that I can do?

Regularly check your oil levels and make sure to change it every 5,000-7,000 miles. This will help keep your engine clean and lubricated.

Take your car for a tune-up every year or every 10,000 miles. This will help identify any potential issues before they become major problems.

Avoid idling for long periods of time as it can cause buildup in your engine and decrease its efficiency.
