How to improve fuel efficiency on a Ford Transit Custom?

I own a Ford Transit Custom and I am looking for ways to improve its fuel efficiency. Any tips or tricks?

One way to improve fuel efficiency on your Ford Transit Custom is to make sure you regularly change your air filter. A dirty air filter can reduce your fuel efficiency by up to 10%.

Another tip is to keep your tires properly inflated. Underinflated tires can reduce fuel efficiency and also increase the wear and tear on your tires.

Avoid excessive idling and aggressive driving. These habits can waste fuel and put unnecessary strain on your vehicle.
