How can I increase my Vauxhall Combo Life's fuel efficiency?

I've noticed that my Vauxhall Combo Life has been consuming more fuel than usual. Is there anything I can do to increase its fuel efficiency?

One way to improve your Vauxhall Combo Life's fuel efficiency is to regularly check and replace your air filter. A clogged air filter can greatly impact your vehicle's fuel efficiency.

Another tip is to avoid aggressive driving and maintain a steady speed on the highway. Rapid acceleration and braking can use up more fuel.

Keep your tires properly inflated to the recommended pressure. Under-inflated tires can decrease your vehicle's fuel efficiency.
