My Uncle was just saying last week that they discovered their Iveco Eurostar was only returning 4 mpg talk about been very annoyed Lol it’s on Lease from Bells of Ashington and although it’s due for replacing in June he was saying it’ll be cheaper to stand it in the yard till the replacement motor arrives 
Bells reckon they cant find anything wrong with it, i.e injectors okay and no leaks etc 
I know thats plated at 44 ton but could’nt tell you the exact model or specs to it.
No doubt wait until June and call in a Bells and you’ll see it
