How do I optimize the fuel efficiency of my Ford Transit Custom?

I recently purchased a Ford Transit Custom for my small business. I have noticed that it consumes a lot more fuel than I expected. Are there any tips or tricks to increase its fuel efficiency?

As a car enthusiast, I would recommend that you regularly check and replace your air filter. A dirty air filter can significantly impact your fuel efficiency. Additionally, make sure your tires are properly inflated to reduce drag and improve fuel economy.

Another thing you can do is avoid idling for long periods of time. If you need to wait for more than 10 seconds, it is more fuel-efficient to turn off your engine and restart it when you're ready to go.

Try to minimize driving at high speeds or accelerating too quickly. These actions can increase your fuel consumption by up to 25%. Instead, try to maintain a steady speed and use cruise control on the highway.
