How can I increase my Vauxhall Vivaro's fuel efficiency?

I recently purchased a Vauxhall Vivaro and I've noticed it's not as fuel efficient as I expected. Are there any tips or modifications I can make to increase its fuel efficiency?

One way to increase your Vauxhall Vivaro's fuel efficiency is to regularly maintain and service your vehicle. This includes changing the oil, air filter, and spark plugs as recommended by the manufacturer. Additionally, keeping your tires properly inflated can also improve fuel efficiency.

Another tip is to avoid idling your vehicle for long periods of time. If you anticipate being stopped for more than a minute, it's better to turn off the engine and turn it back on when you're ready to continue driving. This can save a significant amount of fuel over time.

Consider adjusting your driving habits to be more fuel efficient. This includes avoiding sudden accelerations and heavy braking, as well as maintaining a steady speed. You can also try using cruise control on long stretches of highway to maintain a consistent speed.
