What MPG should we expect from a Euro 5 130 on a Fiat Ducato? Overcab 3500Kg, 7 metres long 2013 model. Dealer says his hire vehicles, same van are just shy of 30 mpg ours is averaging 24.2. Both the computer and manual calculations are the same. This mpg does not vary on long or short trips travelling at 55 mph roughly on long trips. We did expect more. It drives beautifully and has a lot of torque without having to push it. Bit disappointed I suppose.
