Tips on pumping petrol
By katak | December 15, 2007
I received a forwarded message from Mdm Aini, who will be leaving for pilgrimage this Thursday. With the influx in petrol prices, these tips will probably come in handy for most motorists out there.
#1: Only buy or fill up your car or truck in the early morning when the ground temperature is still cold.
Remember that all service stations have their storage tanks buried below ground. The colder the ground the more dense the gasoline, when it gets warmer gasoline expands, so buying in the afternoon or in the evening, your gallon is not exactly a gallon.
In the petroleum business, the specific gravity and the temperature of the gasoline, diesel and jet fuel, ethanol and other petroleum products plays an important role. A 1-degree rise in temperature is a big deal for this business.
But the service stations do not have temperature compensation at the pumps.
#2: When you’re filling up do not squeeze the trigger of the nozzle to a fast mode.
If you look you will see that the trigger has three (3) stages: low, middle, and high. In slow mode you should be pumping on low speed, thereby minimizing the vapours that are created while you are pumping.
All hoses at the pump have a vapor return. If you are pumping on the fast rate, some of the liquid that goes to your tank becomes vapour. Those vapours are being sucked up and back into the underground storage tank so you’re getting less worth for your money.
#3: One of the most important tips is to fill up when your oil tank is HALF FULL or HALF EMPTY.
The reason for this is, the more petrol you have in your tank the less air occupying its empty space. Petrol evaporates faster than you can imagine. Petrol storage tanks have an internal floating roof. This roof serves as zero clearance between the petrol and the atmosphere, so it minimizes the evaporation.
#4: If there is a petrol truck pumping into the storage tanks when you stop to buy petrol, DO NOT fill up.
This is because the petrol is being stirred up as the storage petrol is being delivered, and you might pick up some of the dirt that normally settles on the bottom.
