Cooper D-07 High fuel consumption.
I have noticed that my consumption is fairly high and not in line with the onboard computer.
The onboard computer is showing an awarage of 4.2-4.5l/100km (67.27-62.77mpg) but when I fill the tank and divide by the milage I get around 5.1-5.6l/100km (55.38-50.40mpg)
Is this normal that is deviates so much? And is this not a fairly high consumption?
The driving style is extremely gentle, commuting highway with speeds ranging from 80-110km/h (50-68mph) and around 2x 50km (31mi) a day. Free flowing traffic, almost no city driving.

Tire pressure on the high side.
185000km (115000mi) on the clock
Any suggestions to lower my consumption and why itīs not in line with the onboard computer?
