How often should I change the oil on my Nissan Micra?

I just purchased a Nissan Micra and I'm not sure how often I should be changing the oil. Can you give me some guidance on the recommended maintenance schedule?

It's recommended to change the oil in your Nissan Micra every 5,000-7,500 miles or every 6 months, whichever comes first.

If you often drive in harsh conditions, such as extreme temperatures or dusty roads, it's best to change the oil every 3,000 miles.
