And for what? Honestly, it's always amazed me that so many people flock to the petrol stations to fill up just before the increase because I'm doubtful they reckon the savings.
For example, we're expecting a 28c/litre increase at midnight tonight, so a friend of mine urges us to fill up to save money, and I'm sure most people think the same way.
Let's take a few calculations into effect here:
On a 40l tank, that's R11.20 extra per tank, or in this case if you were on 0l when you filled up, a once-off saving of R11.20.
On a 80l tank, that's R22.40 extra per tank, or in this case if you were on 0l when you filled up, a once-off saving of R22.40.
On a 100l tank, that's R28 extra per tank, or in this case if you were on 0l when you filled up, a once-off saving of R28.
First of all, I'm pretty sure no-one is totally dry when they reach the station, so they'll only incur a fraction of the savings listed above. If people are on average half-full (or half-empty) when they go, the 40l owner saves R5.60, 80l saves R11.20 and 100l owner saves R14.
This leads to my second and final point on the matter: if you're driving the 100l car, I'm pretty sure that making an out-of-the-way trip to the service station is going to use up more time than the R14 saving would be worth to you, not so?
PS: compliments of the season!
