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

I recently purchased a Ford Transit Custom and I'm concerned about the fuel efficiency. What steps can I take to improve it?

Regularly servicing your vehicle can greatly improve its fuel efficiency. Make sure to follow the manufacturer's recommended maintenance schedule.

Good driving habits such as avoiding sudden acceleration and braking can also help improve fuel efficiency. Try to maintain a consistent speed while driving.

Consider investing in fuel efficient tires and keeping them properly inflated. This can have a significant impact on fuel efficiency.

Using cruise control on the highway can also help improve fuel efficiency by maintaining a consistent speed and reducing unnecessary acceleration.
