V70 2015MY D5 6speed man.215bhp

Almost never used for journeys under 20 miles (had old Jazz for that) 70k miles, central console infront of driver shows 49.3mpg. Never been able to reset it,now don't try. In the display which houses the navigation maps there's a setting which allows mpg to be shown for each journey. Anything over 50+miles on dual carriage way + motorway it will return 55+mpg.
Cheers bob
