Hi Conman,

I have an S Line 2.0TDi 170 saloon and I have done nearly 6000 miles since new. My mpg as measured on the DiS is about 50 and the calculated at each fill up figure is about 47-48. I am not a granny nor a boy racer, but I think I am sensible and do anticipate slow down and speed up events. My mpg has suffered in the bad weather we have had in the North of Scotland lately, but it has not dropped below 43 even in the worst conditions.

Hope this helps

TAF
