What is the best way to maintain the fuel efficiency of my Vauxhall Combo Life?

I have recently purchased a Vauxhall Combo Life and I am concerned about maintaining its fuel efficiency. Can anyone give me some tips on how to improve and maintain the fuel economy of my vehicle?

Regularly service your vehicle and make sure your tires are properly inflated. This can greatly improve your fuel efficiency.

Avoid aggressive driving and accelerating quickly as this can decrease your fuel efficiency.

Consider removing any unnecessary weight from your vehicle, as this can also impact fuel economy.
