How can I improve the fuel efficiency of my Vauxhall Crossland?

I have noticed that my Vauxhall Crossland is not as fuel efficient as it used to be. What can I do to improve its fuel efficiency and save on gas costs?

Regularly maintain your car and make sure it is running at its optimal level. This includes checking and replacing air filters, spark plugs, and tires.

Avoid idling your car for extended periods of time. This wastes fuel and also pollutes the environment.

Drive at a constant speed and avoid sudden accelerations and braking. These actions waste fuel and also put more strain on your car's engine.
