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

I've noticed that my Vauxhall Crossland seems to use a lot of gas and I was wondering if there were any specific techniques or tips that could help me improve my gas mileage. I also want to be sure that my driving habits aren't negatively impacting my car's fuel efficiency.

One way to improve your gas mileage is to make sure your tires are properly inflated. Under-inflated tires can decrease fuel efficiency. Regularly check your tire pressure and fill up as needed.

Another tip is to avoid unnecessary idling. If you're going to be stopped for more than 30 seconds, it's more fuel-efficient to turn off your engine and start it back up when you're ready to go.

Maintaining a steady speed can also help improve gas mileage. Avoid accelerating or braking quickly, as this can use up more fuel. Try to maintain a constant speed while driving.
