What is the best engine oil for a Ford Fiesta ST?

I recently purchased a Ford Fiesta ST and I'm looking for the best engine oil to use. I've heard a lot of conflicting opinions and I'm not sure what to go with. Can anyone provide some advice on which engine oil would be the best fit for my car? Thanks!

I would recommend using a synthetic blend oil with a viscosity of 5W-30. This will provide optimal protection and performance for your Ford Fiesta ST.

I've been using fully synthetic oil with a viscosity of 5W-20 and I've had great results. It's important to stick with the recommended oil for your car to ensure the best performance.

I would suggest using a higher quality oil, such as a full synthetic like Mobil 1 or Castrol Edge. These oils may cost a bit more, but they provide better protection and can actually save you money in the long run.
