What is the best oil to use for my Ford Fiesta engine?

I recently bought a secondhand Ford Fiesta and I am not sure what type of oil to use for the engine. I am worried about causing damage if I use the wrong oil. Can someone please advise me on the best type of oil to use for my Ford Fiesta? Thank you.

It is recommended to use synthetic oil for your Ford Fiesta, specifically one that meets the specifications of the owner's manual. This type of oil will provide better protection and performance for your engine.

I have been using conventional oil in my Ford Fiesta and have not encountered any issues so far. However, I have heard that synthetic oil is better for newer engines.
