What is the best way to maintain the fuel efficiency of a Vauxhall Insignia?

I have recently purchased a Vauxhall Insignia and I want to make sure I am taking the necessary steps to maintain its fuel efficiency. How can I achieve this?

The first and most important step in maintaining the fuel efficiency of your Vauxhall Insignia is to keep up with regular maintenance checks. This includes having the engine oil changed, checking the air filter, and ensuring all other fluids are topped up.

Another way to improve the fuel efficiency of your Vauxhall Insignia is to keep the tires properly inflated. Underinflated tires can increase fuel consumption by up to 5%.

To further optimize the fuel efficiency of your Vauxhall Insignia, try to avoid heavy loads and unnecessary idling. The more weight your car has to carry, the more fuel it will use. And idling for too long is also a waste of fuel.
