Recently, a picture posted on the SG Road Vigilant Facebook group went viral because it showed a Singapore-registered car being refueled at a petrol station in Malaysia when its rear wheels were raised on a wooden ramp.
Oddly enough, this practice is not uncommon because other motorists have done the same thing in the past since the reopening of the land border between Malaysia and Singapore on April 1 this year. Even before the epidemic hit and borders were opened, there was no shortage of these so-called dakar posts on social media. Kiyasu Motorist
In addition to using a ramp, some motorists are also known to use a car jack to literally “shake” their car to raise the rear of the car or at the pump. The reason for this activity is to put as much fuel into the tank as possible, so much so that the overfilling target.
Petrol prices in Malaysia are significantly cheaper than in Singapore – RON 97 (minimum fuel grade Singaporeans have to pump in Malaysia) RM3.94 per liter whereas for RON 95 it is around SGD3.13 (RM9.86). (RON 98 more expensive) – Pressing every last drop of an affordable item in the tank can seem like a “tricky hack”.
It’s not. The reality is that the negative effects of overfilling your car’s fuel tank outweigh the perceived benefits of getting a little more range. First, overfilling can damage your vehicle because it can overwhelm the Evaporative Emission System (EVAP), which is designed to store and dispose of fuel vapor before it is released into the atmosphere.
Overfilling can cause liquid fuel to enter EVAP’s charcoal canister (or carbon filter), which is designed for steam only, damaging it and other potential parts of the system, resulting in quite expensive repair bills.
So, the next time you hear a click from the fuel nozzle, it’s probably a good indication that your tank is full and you don’t need to force feed your car. If your car’s fuel tank can only hold 40 liters, you can’t expect your car to be tactful with the pitch, roll, and yaw and shake up to an extra 10 liters, right?
