How to improve mileage in my Vauxhall Insignia?

I have been noticing that the mileage on my Vauxhall Insignia has been declining. What can I do to improve it?

Regularly check your tire pressure and make sure they are properly inflated. Under-inflated tires can decrease your mileage.

Avoid rapid acceleration and braking, as this can decrease your mileage. Try to maintain a steady speed while driving.

Make sure your engine is properly tuned and any necessary repairs are done. A well-maintained engine can improve your mileage.
