How can I improve fuel efficiency in my Ford Transit Custom?

I recently purchased a Ford Transit Custom and have noticed that I am using a lot of fuel. Is there anything I can do to improve the fuel efficiency of my vehicle?

One way to improve fuel efficiency is to make sure your tires are properly inflated. This can help reduce rolling resistance and improve gas mileage.

Another tip is to avoid idling for long periods of time. Turning off your engine when parked or waiting can save on fuel consumption.

Regular maintenance, such as oil changes, can also help improve fuel efficiency in your Ford Transit Custom.
