This subject has come up many times and i have replied to some comments made by members on their figures.First of all i have quoted that over 31000 miles my average for our Octy A2 2.0 dsg has been 41 mpg of which 6000 miles has been towing 1350 klg caravan.My screen tells me that i am up in the higher 50/60 mpg when travelling but on the last tank load from full it had 468 miles on the clock and saying 20 miles to go before empty, i put 51 litre in which filled it up and it still worked out at approx' 41 mpg and yet you guy's often say the screen :rotz:reading are near enough correct. What do you think?>
