How can I improve fuel economy in my Vauxhall Insignia?

I'm struggling with high fuel costs and I know the Vauxhall Insignia is supposed to have good fuel efficiency. What can I do to improve my car's fuel economy?

First, make sure you're following the recommended maintenance schedule for your Insignia. Keeping your car in good shape can improve your fuel efficiency.

You can also try using a fuel additive or fuel cleaner designed specifically for your Vauxhall Insignia. This can help clean out any buildup in your engine and improve fuel efficiency.

Check your tire pressure regularly, as underinflated tires can decrease fuel efficiency. Keep them at the recommended pressure for your car.

Avoid aggressive driving and try to maintain a consistent speed while driving. This can also help improve fuel economy.
