Starting this fill I use a new method of computing the KM/Liter. Previously, I use the last liter filled with the current traveled KM. I could not recall why I compute it that way. Anyway, Since I fill every tank full up to the brim, by using the current liter filled and current traveled KM will be more accurate depicting how much liter were consumed in the traveled KM. Comparing this new method with the onboard computer, there is a huge difference. However, the onboard computer difference comparing to the manual method have not be fairly accurate anyway, and have the similar variance.
