How often should you change your Ford Mondeo's oil?

I recently purchased a Ford Mondeo and I'm not sure how often I should change the oil. I've been told different things by different people. What's the best practice?

It's recommended to change the oil every 7,500 miles or once a year, whichever comes first.

I change my Ford Mondeo's oil every 5,000 miles to be safe. Oil is cheap compared to engine repairs.

I change the oil every 10,000 miles on my Ford Mondeo and haven't had any issues. Just make sure to use high quality oil.
