Some tips for filling petrol and diesel: -

Only buy or fill up your car or bike during early morning, when the ground temperature is still cold. Remember that all service stations have their storage tanks underground.. The colder the ground, the more dense the fuel. When it gets warmer, petrol expands. So, buying in the afternoon or in the evening, your litre is not exactly a litre. In the petroleum business, the specific gravity and the temperature play an important role. 1 degree rise in temperature is a big deal for this business. But the service stations do not have temperature compensation at the pumps.


Another most important tip is to fill up when your tank is HALF FULL. The reason for this is, the more fuel you have in your tank the less is the air occupying its empty space. Petrol evaporates faster than you can imagine.

Another useful information is to avoid filling up if there is a fuel truck pumping into the storage tanks when you stop to buy. Most likely, the petrol/diesel is being stirred up as the fuel is being delivered, and you might pick up some of the dirt that normally settles on the bottom.

Hope this will help you get the most value for your money.

Do not pump full tank of petrol

Many of us are not aware that the petrol kiosk pump has a return pipe-line (in Pink ). 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/CALTEX/MOBIL/ PETRONAS
