With the usual media coverage of petrol price rises over Easter (yes, that’s how the market economy works… when demand goes up, so do prices…), I was pondering how much money I’ve been spending on petrol.
The car barely goes anywhere on weekdays, and even on the weekends I’m doing perhaps around 50 kilometres.
Given I never pay cash at petrol stations, I had a quick skim through my credit card history to see how often I fill up. And the answer is that the median number of days between fills is 27.5 days. (Usually I don’t bother going in unless the tank is under about 15% full.)
Sometimes it’ll be as short as a week or so between petrol visits — such as over the Christmas period when there’s often a trip or two up to the country. But at other times I’ll go as much as 42 days between refills.
I also worked out that I’ve spent $716.26 on petrol in the past year, and my median petrol cost per day is $1.71… so I suppose about 1.3 litres at current costs.
But I’m lucky enough that most of the time, I simply don’t use much petrol, because most of my trips each week are either on foot or on PT.
Be nice if more people had that option.
