What is the best way to maximize fuel efficiency in a Ford Transit Custom?

I just purchased a Ford Transit Custom and am wondering about tips and tricks for improving fuel efficiency. This is my first Ford car and I want to make sure I take care of it properly so any advice would be greatly appreciated.

One of the best ways to improve fuel efficiency in any car, including the Ford Transit Custom, is to practice good driving habits. This includes avoiding rapid accelerations and excessive idling, as both of these can lead to increased fuel consumption.

Another tip for maximizing fuel efficiency is to keep your car properly maintained. This means regularly checking and replacing air filters, spark plugs, and tires. By keeping your car in good shape, you can ensure it's running as efficiently as possible.

Using cruise control on the highway can also help improve fuel efficiency. By maintaining a constant speed, your car won't have to work as hard and will use less fuel.
