So guys i topped up fuel tank of my gli 2010 n traveled 600km highway travel. The on-board mileage calculator was showing average of 12.7 km/l. On culmination of journey i topped up the tank again n it got filled with 40 litres.
600km in 40 litres gives average of 15.
My query is why there is so much variation between the actual mileage n the one given by on board computer. Can we do something to improve its accuracy? Needless to say that I reset trip meter, average n time elapsed meter before start of travel.
