What is the best oil to use in a Ford Fiesta ST?

I just bought a Ford Fiesta ST and I want to make sure I am taking proper care of the engine. What type of oil should I use and how often should I change it?

It is recommended to use a fully synthetic oil with the viscosity grade of 5W-30 for your Ford Fiesta ST. You should change the oil every 5,000 miles or every 6 months, whichever comes first.

I've personally used Mobil 1 5W-30 synthetic oil in my Ford Fiesta ST and have had great results. Just make sure to follow the recommended change interval and you should be good to go!

I always stick to the manufacturer's recommended oil for my Ford Fiesta ST. The 5W-30 synthetic oil is what Ford recommends and I've never had any issues with it.
