How to maintain the fuel efficiency of my Ford Fiesta?

I recently bought a Ford Fiesta and I want to make sure that I maintain its fuel efficiency. Can you suggest some tips and advice on how to achieve this?

To maintain the fuel efficiency of your Ford Fiesta, make sure to regularly change the engine oil and air filter. Also, ensure that your tires are properly inflated and avoid idling for long periods of time.

One effective way to improve fuel efficiency is by avoiding unnecessary weight in your car. Remove any heavy items from your trunk and avoid excessive cargo on your roof.

Keeping a consistent speed while driving can also help improve fuel efficiency. Avoid sudden accelerations and decelerations as this can use up more fuel.
