How to increase mileage in a Vauxhall Zafira Life?

I have noticed that my Vauxhall Zafira Life is not giving the mileage it used to. What could be the reason for this and how can I improve it?

One common reason for a decrease in mileage could be a clogged air filter. Check and replace it if necessary.

Regularly maintaining your Vauxhall Zafira Life by getting timely oil changes and tune-ups can also help improve mileage.

Avoid excessive idling and aggressive driving to save fuel and improve mileage.

Using the recommended grade of engine oil and keeping your tires properly inflated can also make a difference in your vehicle's mileage.
