How to improve the fuel efficiency of a Vauxhall Movano?

I am looking for ways to increase the fuel efficiency of my Vauxhall Movano. I am currently getting lower mileage than the advertised numbers. Can you suggest any tips or modifications that will help me save on fuel costs?

Firstly, ensure that your Movano is properly tuned up and serviced regularly. This can significantly improve fuel efficiency.

In addition, check your tire pressure regularly and make sure they are properly inflated. Underinflated tires can reduce fuel efficiency.

Consider using higher quality motor oil for your Movano. It can help with fuel efficiency and improve engine performance.

Avoid idling for long periods of time. Turn off your engine if you are going to be stationary for more than a minute.

Avoid aggressive driving such as rapid acceleration and harsh braking. This can negatively impact fuel efficiency.
