How to improve gas mileage in a Vauxhall Zafira Life?

I just purchased a Vauxhall Zafira Life and I feel like the gas mileage is not as good as expected. What can I do to improve it?

First, make sure you are using the recommended fuel type for your car. Using a lower quality fuel can decrease gas mileage.

Regular maintenance, such as changing the air filter and getting your tires properly inflated, can also improve gas mileage.

Avoid aggressive driving habits, such as sudden acceleration and braking, as these can significantly decrease gas mileage.
