How do I improve fuel efficiency in my Vauxhall Crossland?

I've noticed my Vauxhall Crossland is using more fuel than usual. What steps can I take to improve its fuel efficiency?

Regular maintenance and tune-ups can help improve fuel efficiency. Make sure to change your air filter and fuel filter regularly.

Avoid idling for long periods of time. If you know you will be stopped for more than a minute, it's better to turn off your engine.

Check your tires regularly and make sure they are properly inflated. Under-inflated tires can decrease fuel efficiency.

Consider reducing the weight in your car, such as removing unnecessary items from your trunk. The lighter your car, the better its fuel efficiency.
