What MPG figures are achieved by your 1.9CDTI? The figure we are looking for is the mixed driving, ie a bit of round the town, to the shops etc mixed in with a fast flowing A road or Motorway. This is the figure referred to as 'combined' in most manufacturers litreature and the most relevent indicator of the most common use of the car.
We'll then take the average and compare this real life figure to what Vauxhall claim and see if they got it right.
