How to improve the fuel efficiency of my Ford Fiesta ST?

I recently purchased a Ford Fiesta ST and I love the power and handling, but I'm concerned about the fuel efficiency. What are some tips and tricks to improve the gas mileage on my Fiesta while still enjoying its performance?

First, make sure you're using the recommended grade of gasoline for your Fiesta ST. Using a higher octane fuel can improve fuel efficiency. Also, try to avoid aggressive acceleration and braking as it uses more fuel. Additionally, keeping your tires properly inflated and performing regular maintenance can also help with fuel efficiency.

I suggest using cruise control on long highway drives to maintain a consistent speed and reduce fuel consumption. Another thing to consider is using a fuel additive, such as a fuel injector cleaner, to keep your engine running smoothly and improve efficiency.
