My Honda City

Petrol: Caltex Techtron

Liter Filled: 40.60 liter
Distance Traveled: 535.8 km
Onboard Computer KM/Liter: 14.5 km/liter
Manually Computed KM/Liter: 13.2 km/liter

This is the second fill I use the new computation method, and again, it has a huge difference between the Onboard Computer and manually computed KM/Liter. Theoretically, the new computation method should be more accurate, but it differs the onboard computer. Will moniter a few more fill on this..
