It has been some time since I shared on my car fuel consumption performance. I have device a new method of computing the fuel consumption. What I do now is to pump a fix value each time, in this case, I always pump 26.04 liter. This value is based on RM50 @ RM1.92/Liter. For each of the fueling instances on the x-axis, I pump 26.04 liter and drive the car till it’s empty, which is till the light comes up and the indicator go to the lowest, most of the time hitting E and below. Then I pump 26.04 liter again. I find that by doing this, the fuel consumption are pretty stable at the average of 14.5km/liter and a Standard Deviation of 0.59. My stock tires which are Goodyear RCT are going bald and I will be changing them soon. Currently I am eyeing on Continental Contact 2 or Michelin Preceda 2. The Tires manufacturer always claim that their tires safe fuel, etc.. well, I will be putting them to the test. I will compare the fuel consumption before and after the tire change. Since I will be changing all 4 tires at one go, it would be a good estimate to see if what the manufacturers claim are valid. Oh, by the way, instance 2 and 3 was Caltex Techron and the rest were Shell Super.

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.

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..

After using Shell V-power for sometime, I got tired of paying the premium price. I decided to give Caltex Techron a go, after some recomendations from my friends. I was imediately converted. When I pull out of the gas station, I did not feel any power loss, and this was a huge difference with the other brands of Ron 97 (Shell Super, Petronas Primax 2, etc.). In another words, the Caltex Techron felt like Shell V-power, which was amazing. I decided to stop using Shell V-power, mainly because my pocket could not support the premium price, and the benefit of power and mileage is not little over regular Ron 97 fuel.
