How can I improve my gas mileage with my Vauxhall Crossland?

I just bought a Vauxhall Crossland and I noticed that my gas mileage isn't as good as I had hoped. Is there anything I can do to improve it? Any specific maintenance or driving habits I should be aware of?

Maintain your tire pressure regularly. Under-inflated tires can decrease fuel efficiency. Also, accelerate smoothly rather than quickly and avoid excessive idling.

Don't carry unnecessary weight and avoid using roof racks when you can. This can put extra stress on your engine and decrease gas mileage.

Follow recommended maintenance schedules and use high-quality fuel and oil. This can help keep your engine running efficiently and improve gas mileage.
