How to improve fuel efficiency on the Vauxhall Insignia?

I recently purchased a Vauxhall Insignia and I am interested in optimizing its fuel efficiency. Are there any specific tips or modifications that I can make to achieve better mileage?

One simple tip is to make sure your tires are properly inflated. Under-inflated tires can significantly decrease fuel efficiency.

Another way to improve fuel efficiency is to avoid unnecessary idling, especially during traffic jams or long traffic lights.

Regular maintenance, such as oil changes and air filter replacements, can also contribute to better fuel efficiency.
