How can I improve my Vauxhall Mokka's fuel efficiency?

I have noticed that I am constantly having to refill my Vauxhall Mokka's gas tank. Is there anything I can do to improve its fuel efficiency?

Regularly maintain your car by getting tune-ups and oil changes. This can greatly improve your fuel efficiency.

Avoid aggressive driving habits, such as rapid acceleration and braking. This can use up a lot of gas.

Check your tire pressure regularly. Under-inflated tires can cause your car to use more gas.
