How can I increase the fuel efficiency of my Vauxhall Corsa?

I have been noticing that my Vauxhall Corsa's fuel consumption is higher than usual. What can I do to improve its fuel efficiency?

Regularly check and replace your air filter. A dirty air filter can decrease fuel efficiency.

Ensure that your tires are properly inflated. Under-inflated tires can increase fuel consumption.

Avoid aggressive driving and sudden acceleration. This can significantly impact your fuel efficiency.

Try using a fuel injector cleaner to improve your car's performance and fuel efficiency.
