My Honda City

I have not been updating on the fuel consumption since early in the year, but I am still keeping tabs. Above is the latest fuel consumption figures up to May. The average is still hovering around 14.5km/l. It seams like since the last service, the km/l is trending up. But lets monitor how this goes. I will also compare between the previous service and this service to see if there are any difference in consumption. For the latest service, I have used my own Idematsu Fully Synthetic oil instead of Honda Service Center’s Vtec Fully Synthetic oil, which was reportedly to be Idematsu also.

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.

I’ve found a sweet spot for the City Vtec Fuel Consumption, which is to travel at a 80-90kmph. Recently, I’ve made a trip to the East of Malaysia and had to travel through mountainous and village roads. There were no Highway, and so I had to travel at 80-90kmph all the way. I manage to clock 721km with 35liter of fuel. This is the record distance I’ve made with the My Honda City Vtec. At this sweet speed, the RPM is about 2k and this is also when the 7th gear kicks in. An amazing discovery, and this will be my future travel speed. At times of when the fuel price is high, arriving the destination a little late is ok.
