How to increase fuel efficiency in the Ford Transit Custom?

I'm constantly having to refill my Ford Transit Custom's fuel tank, is there any way to increase its fuel efficiency?

One way to increase fuel efficiency in your Ford Transit Custom is by regularly maintaining your vehicle, such as changing your oil and air filter.

Another tip is to avoid idling for an extended period of time and keep an eye on your tire pressure. Both of these can have an impact on your fuel consumption.

It may also be helpful to avoid carrying excess weight in your vehicle and to drive at a constant speed as much as possible.
