How can I increase fuel efficiency on my Vauxhall Movano?

I've noticed that my Vauxhall Movano is not getting great gas mileage. Is there anything I can do to improve its fuel efficiency?

One way to improve fuel efficiency is to regularly check and replace your air filter. A dirty air filter can decrease fuel efficiency by up to 20%.

Make sure to keep your tires properly inflated. Underinflated tires can decrease fuel efficiency by as much as 3%.

Avoid aggressive driving and excessive idling. These behaviors can greatly decrease fuel efficiency.

Consider using a fuel system cleaner to remove any build-up in your engine that may be reducing fuel efficiency.

Have your vehicle serviced regularly to ensure all components are working properly and efficiently.
