How can I increase the fuel efficiency of my Vauxhall Movano?

I recently purchased a Vauxhall Movano and I've noticed that it's not as fuel efficient as I would like. Are there any specific maintenance or driving habits I should be aware of that can help improve its fuel efficiency?

One way to improve fuel efficiency is to make sure your tires are properly inflated. Under-inflated tires can increase fuel consumption.

Regular oil changes can also help improve fuel efficiency. Dirty or old oil can cause the engine to work harder and use more fuel.

Avoid excessive idling and abrupt accelerations. These driving habits can significantly decrease fuel efficiency.
