* Engine size and type: Transit vans come with a range of gasoline and diesel engines, each with different fuel efficiency. Diesel engines generally offer better fuel economy than gasoline engines.
* Vehicle weight: A van loaded to its maximum capacity will get considerably worse fuel economy than an empty van.
* Driving style: Aggressive driving significantly reduces fuel efficiency.
* Terrain: Driving in hilly or mountainous areas reduces fuel economy compared to flat terrain.
* Year and Model: Fuel economy standards and engine technology have improved over the years.
Therefore, there's no single answer. You'll find a range of figures quoted, typically between 15 and 25 MPG. However, it's best to consult the EPA's FuelEconomy.gov website or the owner's manual for the specific year and model of the Transit van you're interested in for the most accurate MPG figures.
