What is the best way to improve the fuel efficiency of a Ford Transit Custom?

I recently purchased a Ford Transit Custom for my business, but I'm looking for ways to save money on fuel. Any tips or tricks to increase the fuel efficiency of my Ford Transit Custom?

One of the best ways to improve fuel efficiency is by keeping your vehicle well-maintained. This includes regular oil changes, tire rotations, and tune-ups.

Avoid idling for long periods of time and try to plan your routes efficiently to minimize unnecessary driving. Also, make sure your tires are properly inflated to improve fuel economy.
