How to increase the fuel efficiency of my Ford Puma?

I recently purchased a Ford Puma and I'm concerned about the low fuel efficiency. Can anyone provide some tips on how to improve it without affecting the performance?

One of the easiest ways to increase fuel efficiency is to make sure your tires are properly inflated. Under-inflated tires can decrease fuel efficiency by up to 3%. Also, try to avoid excessive idling and use cruise control on long highway drives.

Regular maintenance, such as oil changes and air filter replacements, can greatly improve fuel efficiency. Also, try to remove any unnecessary weight from your car, as this can also affect the fuel consumption.
