Is it better to use high-octane fuel for my Ford Fiesta?

I recently purchased a Ford Fiesta and I'm wondering if using high-octane fuel is necessary or beneficial for my car's performance. Will it improve gas mileage or is it just a waste of money?

Using high-octane fuel may lead to a slight increase in horsepower and acceleration, but it is unlikely to have a significant impact on overall performance. It may also improve fuel efficiency in certain driving conditions, but the cost-benefit ratio may not be worth it.

The type of fuel you use depends on the specific engine and design of your car. It's always best to refer to your owner's manual for recommended fuel. If your Ford Fiesta is designed to use regular gasoline, there is no need to switch to high-octane unless you experience engine knocking or pinging.

I have been using high-octane fuel in my Ford Fiesta for years and I have definitely noticed a difference in performance. It's a personal choice, but if you have the extra money to spend on premium fuel, go for it.
