What's the best way to maintain the engine of a Nissan Micra?

I recently bought a used Nissan Micra and I want to make sure I'm properly maintaining the engine to ensure it lasts. What are some tips or regular maintenance tasks I should be doing to keep the engine running smoothly?

Regularly check and change the oil according to your owner's manual. This will help keep your engine lubricated and running smoothly.

Make sure to regularly check and replace your air filter. A dirty air filter can negatively impact your engine's performance.

In addition to regular maintenance, consider using a fuel additive to keep your engine clean and improve fuel efficiency.
