What is the best oil type for a Ford Galaxy and how often should it be changed?

I have a Ford Galaxy and I am wondering what type of oil is best for this car and how often should I change it? I don't know much about cars and want to make sure I am doing what's best for my car's engine.

As a car mechanic, I recommend using synthetic oil for your Ford Galaxy. It can last longer and provide better protection for your engine.

I have been using conventional oil for my Ford Galaxy and have had no issues so far. It's more affordable and still gets the job done.
