How can I improve the fuel efficiency on my Vauxhall Astra?

I've noticed that my Vauxhall Astra is using a lot more fuel than usual. Is there anything I can do to improve its fuel efficiency?

Firstly, make sure your tires are properly inflated. Under-inflated tires can significantly impact fuel efficiency. Another tip is to avoid excessive idling and quick acceleration. Additionally, regular maintenance such as oil changes and air filter replacements can also help improve fuel efficiency.

You can also try using a fuel additive or using a higher octane fuel to see if it makes a difference. And don't forget to regularly check your fuel cap to make sure it's properly sealed!

Lastly, try to limit the weight in your car and avoid unnecessary items in the trunk. The heavier your car, the more fuel it will use.
