How can I maximize fuel efficiency in my Vauxhall Insignia?

I have recently purchased a Vauxhall Insignia and I want to make sure I am getting the best fuel efficiency possible. What steps can I take to achieve this?

Regularly checking and maintaining tire pressure can greatly improve your fuel efficiency. Make sure to adjust the pressure according to your car manufacturer's recommendations.

Avoid idling for extended periods of time, as this can waste fuel. If you know you will be stopped for more than a minute, turn off your engine.

Using cruise control on the highway can help maintain a steady speed and improve fuel efficiency. Just make sure to turn it off when driving in hilly or unpredictable terrain.
