How to improve the fuel efficiency of my Vauxhall Zafira Life?

I have been noticing that my Vauxhall Zafira Life consumes a lot of fuel lately. Is there anything I can do to improve its fuel efficiency and save on gas expenses?

Regularly check for any leaks in the fuel system and get them fixed immediately. Small leaks can lead to significant loss of fuel over time.

Keep your tires properly inflated at all times. Under-inflated tires can increase fuel consumption by up to 3%. Check the recommended tire pressure in your owner's manual.

Avoid aggressive driving and accelerate slowly. This can improve fuel efficiency by up to 20%.

Get regular tune-ups and maintenance for your engine. A well-maintained engine can improve fuel efficiency by 4%.

Consider installing a fuel efficiency device such as a fuel vaporizer or fuel ionizer. These devices have shown to improve fuel efficiency by up to 10%.
