How to improve the fuel efficiency of a Ford Transit Custom van?

I recently purchased a Ford Transit Custom for my small business and was wondering if there are any ways to improve its fuel efficiency. My daily routes are short distance, but I still find myself filling up the tank frequently. Any tips or suggestions are appreciated!

As an automotive enthusiast and owner of a Ford Transit Custom van myself, I highly recommend investing in a good quality air filter and regularly changing it. A clean air filter can improve fuel efficiency by up to 20%.

Keeping your tires properly inflated can also greatly improve fuel efficiency. Check your tire pressure regularly and make sure they are filled to the recommended level.
