What is the recommended oil type for a Ford Fiesta ST?

As a car enthusiast, I want to take care of my Ford Fiesta ST and make sure it's performing at its best. I've been using conventional oil, but some people are telling me to switch to synthetic. What do you recommend and why?

As a mechanic with over 10 years of experience working on Ford vehicles, I highly recommend using synthetic oil for your Ford Fiesta ST. Not only does it provide better overall engine protection, but it also increases the longevity of your engine.

I've been using conventional oil for my Ford Fiesta ST for the past 5 years and haven't had any issues. As long as you change it regularly and keep up with maintenance, you should be fine.

I've tried both conventional and synthetic oil for my Ford Fiesta ST and honestly didn't notice much of a difference. It ultimately comes down to personal preference and budget.
