How do I optimize the fuel efficiency on my Vauxhall Movano?

I recently bought a Vauxhall Movano and I'm concerned about the fuel efficiency. Do you have any tips or advice on how I can optimize it?

Regular maintenance and keeping your tires properly inflated can greatly improve your fuel efficiency. Make sure to check your tire pressure once a month.

Avoid speeding and aggressive driving. Maintaining a constant speed and avoiding sudden accelerations and decelerations can greatly improve your fuel efficiency.

Consider installing a fuel efficiency chip or device. These can help optimize your engine's performance and improve your fuel efficiency.
