This fill is when we did the convoy from KL to M’cca. I had a full load with my parents and sister inlaw fully occupying the back seat, and also the trunk was filled with bags. It was very hard for me to keep up with the convoy on my usual driving style (light feet). I had to press the gas more and also sometimes switch to ‘S’ mode, to keep up with the other cars which have very little load. This consume much fuel and hence, explanation for the low mileage.

This time round, some how with the new fuel consumption computation method, it seams to match up between manual vs on board computer. Much different from the last pump.

Again, the KM/Liter differs between the onboard computer and manual computation. Using back the old computing method, the onboard computer is quite close to the manual computation method. Now the question is, which computation method should I continue to use?

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..
