How to improve fuel efficiency of my Vauxhall Corsa?

I have been noticing that my Vauxhall Corsa has been consuming a lot of fuel lately. How can I improve its fuel efficiency?

Regularly maintain your car and keep up with oil changes and tire pressure checks. This can greatly improve fuel efficiency.

Avoid aggressive driving and try to maintain a consistent speed. Rapid acceleration and braking can lead to higher fuel consumption.

Consider using high-quality fuel and additives to improve fuel efficiency. They may be a bit more expensive, but they can significantly improve your car's performance.
