Hi everybody, I'm not one of those m homers that gets paranoid about mpg but after switching the in dash reading on I was a bit shocked to find my 2009 3.0 tri axle bessacarr returning 17-20 mpg on the motorway at 60mph, compared to my previous 2005 2.8 ducato always around 25-30 mpg ? is this the norm or is this a bit low?, rgds Kevin
