How can I improve my Kia ProCeed's fuel efficiency?

I recently purchased a Kia ProCeed and I am a bit concerned about the fuel efficiency. Is there anything I can do to improve it without sacrificing performance?

One simple way to improve fuel efficiency is by practicing good driving habits, such as avoiding aggressive acceleration and braking.

Regular maintenance, such as changing the air filter and keeping tires properly inflated, can also help improve fuel efficiency.

Consider using a fuel additive or using premium fuel to help improve fuel efficiency.
