How to increase the fuel efficiency of my Ford Transit Custom?

I recently purchased a Ford Transit Custom for my business and have noticed that the fuel efficiency is not as high as I expected. What are some tips and tricks I can use to improve the fuel efficiency of my Ford Transit Custom?

As a fellow Ford Transit Custom owner, I would recommend regularly checking and replacing your air filters. This can greatly improve fuel efficiency.

Another way to increase fuel efficiency is by maintaining proper tire pressure. Underinflated tires can decrease your gas mileage.
