How do I improve the fuel efficiency of my Vauxhall Zafira Life?

I've noticed that I'm not getting as much mileage as I expected with my Vauxhall Zafira Life. What are some tips for improving its fuel efficiency?

First, make sure your tires are properly inflated. Under-inflated tires can decrease fuel efficiency. Also, try to avoid idling for long periods of time.

Another tip is to avoid aggressive driving, such as rapid acceleration and braking. This can significantly decrease your fuel efficiency.

Regular maintenance, such as oil changes and air filter replacements, can also help improve your Vauxhall Zafira Life's fuel efficiency.
