How to improve fuel efficiency on a Vauxhall Corsa?

I've been noticing that my Vauxhall Corsa has been using a lot of fuel lately. What can I do to improve its fuel efficiency?

Regularly check your tire pressure and make sure they are properly inflated. This can help reduce fuel consumption.

Avoid rapid acceleration and harsh braking, as this can also contribute to higher fuel consumption.

Consider using a fuel additive to improve your car's fuel efficiency. Just make sure to do your research and choose one that is compatible with your Vauxhall Corsa.
