How to increase fuel efficiency on my Vauxhall Corsa?

I've been noticing that my Vauxhall Corsa has been using up a lot of fuel lately. Is there anything I can do to increase its fuel efficiency?

Regular maintenance and tune-ups can significantly improve fuel efficiency, as well as keeping your tires properly inflated. You may also want to consider using a fuel additive to help clean out any buildup in your engine.

One way to improve fuel efficiency is to change your driving habits. Avoid hard accelerations and excessive idling. Plan your trips efficiently and try to avoid rush hour traffic. Additionally, removing any excess weight from your car can also save you some fuel.

Consider getting a more aerodynamic aftermarket air filter to replace the stock one. This can help improve air flow and increase fuel efficiency. Also, make sure to change your air filter regularly as a dirty one can decrease fuel efficiency.
