I could do over 60mpg on the motorway in my 2.1TD estate and 13 gallon tank so would do just shy of 800 miles to a tank theoretically and with mods I could have added 10-15% more mpg to that with optimization.
Just a thought a coolant pre heater out a HDi will get it up to an efficient temp faster.
