Completed all 1,350 miles on only three tanks of diesel....!!!
50 litres per fill up, total of 34 gals of diesel used.
1,350 miles divided by 34 gals = 39.7mpg.
Our final leg home was Newquay to just east of Norwich, a total od 425 miles, did the whole journey on a single tank of fuel cruising at 65 mph (just fast enough to stay out the way of the lorries and caravans

Long live the mechanical pump TDI engine !!!
