Regular maintenance is key to maintaining fuel efficiency. Make sure to get your Ford Transit Custom serviced regularly and keep up with oil changes and other recommended maintenance tasks.

Avoid aggressive or high-speed driving as these can greatly impact your vehicle's fuel efficiency. Slow and steady wins the race for efficiency.

Consider using a fuel additive to improve your Ford Transit Custom's fuel efficiency. Just make sure to choose one that is compatible with your vehicle's engine.
