What octane gas should you use with a Ford Fiesta?

For a Ford Fiesta, it is generally recommended to use regular unleaded gasoline with an octane rating of 87. This is sufficient for optimal performance in most models. However, if your specific model has a turbocharged engine, you may want to consult the owner's manual, as it might recommend a higher octane fuel for best performance and efficiency. Always refer to the manufacturer's guidelines for the most accurate information.
