If you've stopped by Johor Bahru petrol stations, you'll notice a certain phenomenon involving Singapore cars.
They get manhandled. A lot.
Sometimes, it's a team effort.
Other times, it's a one-man job.
This time, it's one dude doing... this.
More petrol?
In the early hours of Mar. 26, this man was filmed jostling a Toyota Wish at a petrol station in Gelang Patah, Johor.
As if he's done this a thousand times before, the man leans casually against the boot and rocks his body with ease into the 1300kg vehicle.
While holding a conversation with its other passengers, he appears to throw up a "peace" sign.
Some car owners think that shaking their car allows more petrol to enter the tank.
In true Singapore fashion, those who make the trip all the way to Johor Bahru want to get their money's worth, especially since the three-quarter tank rule for departing vehicles leaves them with only a small volume of the tank to fill.
Shaking the tank is thought to let the air escape or the petrol foam to dissipate, so more petrol can flow in.
But is that really how it works?
Debunking the myth
In an episode of CNA's "Talking Point", car workshop director Vincent Emmanuel Lee proved that shaking one's car does next to nothing to increase its petrol intake.
On the contrary, jerking or overfilling the tank may cause petrol to enter the fuel evaporation system, which costs more money to replace.
When it comes to squeezing in that extra petrol, it's like pouring Coke or beer into a glass.
Just wait for the foam to dissipate on its own before pumping more into the tank.
There's really no need for all that workout.
