How do I improve the fuel efficiency in my Ford Transit Custom?

I just recently bought a Ford Transit Custom and I've noticed that it's not getting the best fuel efficiency. Are there any tips or tricks to improve this in my vehicle?

First, make sure your tire pressure is at the recommended levels as specified in your vehicle's manual. This can greatly affect fuel efficiency. Also, avoid idling your engine for long periods of time and try to maintain a steady speed while driving.

Another way to improve fuel efficiency in your Ford Transit Custom is to keep up with regular maintenance such as oil changes, air filter replacements, and tune-ups. This will help your vehicle run more efficiently and use less fuel.
