How to optimize fuel efficiency in the Vauxhall Crossland?

I've noticed that my Vauxhall Crossland has been consuming more fuel than usual. How can I optimize its fuel efficiency without compromising its performance?

Regular maintenance and upkeep can significantly improve your Vauxhall Crossland's fuel efficiency. Make sure to follow the manufacturer's recommended service schedule and keep the tires properly inflated.

Avoid aggressive driving habits such as sudden acceleration and braking, as these can greatly impact your car's fuel consumption. Drive at a consistent speed and avoid idling for long periods of time.

Keep your car's weight to a minimum by removing any unnecessary items from the trunk. This can also help improve fuel efficiency.

Consider using premium fuels or additives that claim to improve fuel economy. However, make sure to do your research and choose a reputable brand.
