I used to think that fuel efficiency, usually measured in Singapore as km/litre, is a good enough gauge of how well the car & driver (collectively) has delivered in terms of using the amount of fuel required to cover certain distance. A few days ago, I listened to one of the podcasts that a better way of measuring the efficiency of the car and driver, as a whole, is to bring in the cost of fuel into the picture as well.
I went back to my fuel efficiency spreadsheet, did some calculation, and agreed that a better way to judge would be in terms of "$/km" or "$ per km", i.e how much it cost to cover one kilometer of travel.
As illustrated in the chart below, I realized that my "$/km" was highest during March2008, but that was not the highest petrol prices yet; Petrol prices were at the peak during July2008; As for now, I see my "$/km" trending downwards and below the "Petrol Price Line", and I hope to make it stay that way by being watchful with my right foot. And if my "$/km" line continues to stay below "Petrol Price" line, I would deem myself to be less affected by the petrol price.
Some tips on how I achieved my fuel efficiency: -
a) Drive with shoes off; This will provide a better "feel" between the feet and the paddles and muster better control;.
b) Drive without air-conditioning at night and anytime when possible to do so.
c) Anticipate to decelerate ahead of traffic lights and stopping points.
