Are people reporting mpg measured at the pump or what's displayed on the trip computer in the car?

My v70 is returning 41-43mpg on mainly dual carriageway/motorway or country road, little time around town. This is measured at the pump at wach fill up. Trip computer shows 46.5 and hasn't been reset for around 8000miles. I don't drive fast, rarely above 80 on motorway, usually around 70.


Is my v70 with roof rails really 8-10mpg worse than an s60? I know it's heavier and less aerodynamic. How much difference do the roof rails make over those that don't have them?

New intercooler fitted last April made 3-4mpg difference. New magnatec oil put in week before Christmas.
