How can I improve the fuel efficiency in my Vauxhall Insignia?

I've noticed that my Vauxhall Insignia is not performing as efficiently as it used to. What steps can I take to improve its fuel efficiency?

One way to improve fuel efficiency is to regularly maintain your car, such as changing out the air filter and keeping your tires properly inflated. Additionally, try to avoid hard accelerations and keep a consistent speed while driving. This can save you on fuel in the long run.

Another tip is to try and drive during off-peak traffic times. Sitting in bumper to bumper traffic can greatly decrease your fuel efficiency. Also, consider using public transportation or carpooling whenever possible to reduce your carbon footprint.

One often overlooked aspect of fuel efficiency is the weight of your car. Remove any unnecessary items from your trunk and only fill your gas tank with the amount needed for your trip. The less weight your car has to carry, the more efficient it will be.
