For those who are usually telling the pump attendent to pump a full tank for you.. read this.

Many of us are not aware that the petrol kiosk pump has a return pipe-line (in black ). When the petrol tank (in the car) reaches full level, there is a mechanism to trigger off the pump latch and at the same time a return-valve is opened (at the top of the pump station) to allow excess petrol to flow back into the sump. But the return petrol has already pass through the meter, meaning you are donating the petrol back to SHELL/ PETRONAS/ CALTEX/MOBIL..........

 

urban legend. not true. appeared in many many forums and dismissed. wonder which idiot came up with such an idea in the first place. a disgruntle shell employee? haha

 

Point taken.. Im the idiot.

 

haha, no offense la. just saying that this was probably started maybe in the USA by some joker.

 

If it has a return pipeline, then there will be no spillovers if you overfill.

 

Im probably from USA..

 

hahaha
