It’s no secret that Singaporeans pay less for fuel in Malaysia when the exchange rate is factored in. For this group of people (possibly a family), getting as much “cheap” fuel as possible warranted “shaking” their vehicles with great vigor at a petrol station in Taman Pelangi, Johor Bahru.
The humorous incident was captured in a video that has since gone viral on social media. In the video, a woman is refueling while her three companions, including an elderly woman, push the Singapore-registered car up and down.
Such sights are not uncommon, and there have even been instances of Singaporean drivers tipping their cars to grab as much fuel as possible. However, overfilling the vehicle’s gas tank outweighs the perceived benefit of taking extra dips on the road to gain extra kilometers.
The action could damage the car because it floods the evaporative emissions system (EVAP), which is designed to store and process fuel vapors before they are released into the atmosphere. Overfilling can cause liquid fuel to enter the EVAP canister (or carbon filter) designed for vapor, damaging it and possibly other parts of the system, which can require costly repairs.
If you hear the fuel nozzle click, you’re done filling up and there’s no need to keep filling the limited tank with more fuel.
