What is the best way to maintain the engine of my Nissan Micra?

I recently purchased a used Nissan Micra and I want to make sure that the engine is well-maintained. What should I do to ensure optimal engine performance and longevity?

Regularly change the engine oil and filter according to the manufacturer's recommended schedule. This will help keep the engine running smoothly and prevent any build-up of debris.

Make sure to check and top off all fluids - such as coolant, brake fluid, and transmission fluid - regularly. Low fluid levels can cause damage to the engine and affect performance.
