TIPS ON FILLING YOUR CAR(S) (Good information)
Petrol is becoming more and more expensive!
My line of work is inpetroleum for about 31 years now, so here are some tricks to get more of
your money’s worth for every litre.
Here at the Marian Hill Pipeline where I work in Durban , we deliver
about 4 million litres in a 24-hour period thru the pipeline. One day is diesel
the next day is jet fuel, and petrol, LRP and Unleaded. We have 34-storage
tanks here with a total capacity of 16,800,000 litres.
Only buy or fill up your car or bakkie in the early morning
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
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 of the petrol, 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.
When you’re filling up do not squeeze the trigger of the nozzle to a fast
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 vapour 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.
One of the most important tips 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 air
occupying its empty space. petrol evaporates faster than you can imagine.
Petroleum storage tanks have an internal floating roof. This roof serves as
zero clearance between the petrol and the atmosphere, so it minimizes the
evaporation. Unlike service stations, here where I work, every truck that we
load is temperature compensated so that every litre is actually the exact
amount. Another reminder, if there is a fuel truck pumping into the storage
tanks when you stop to buy, DO NOT fill up-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.
