'Tips on Filling your Vehicles...'

This is a Message received from a friend:
I don't know what you guys are paying for petrol... but here in Durban, we are also paying higher, up
to 47.35 per litre. But my line of work is in petroleum 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 BIKKIE 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 denser 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 play an important role. A 1degree 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 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 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 maximum value for your money.
