How to improve fuel efficiency of Ford Fiesta?

I recently bought a Ford Fiesta and I am concerned about its fuel efficiency. Is there anything I can do to improve it?

One of the easiest ways to improve fuel efficiency is by keeping your tires properly inflated. This reduces rolling resistance and can save you up to 3% on fuel.

Another tip is to avoid excess idling. If you're stuck in traffic or waiting for someone, turn off your engine instead of letting it run. This can save a significant amount of fuel over time.
