How do I get better gas mileage in my Ford Transit Custom?

I recently purchased a Ford Transit Custom and I noticed the gas mileage is not as good as I expected. What are some tips and tricks to improve my fuel efficiency?

One way to improve your gas mileage is to keep your vehicle properly maintained. Regular oil changes, tire rotations, and air filter replacements can significantly improve fuel efficiency.

Another tip is to avoid idling for long periods of time. If you are stuck in traffic or waiting for someone, turn off your engine. This can save a significant amount of gas in the long run.

You can also try using cruise control on the highway to maintain a consistent speed. This can help save gas by avoiding sudden acceleration and deceleration.
