YOU ARE HELPING TO CHEAT YOURSELF

Recently I came across a very useful
tip. I was surprised to know it but
had a doubt so I talked to one of
the pump technicians and he too
accepted it as a fact. I think apart
from providing space for the gas
generated inside the petrol tank this
is yet another reason why we
shouldn't fill the tank to the brim.
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 pump.
But the return petrol has already
pass through the meter, meaning
you are donating the petrol back to
the Oil Dealer.
Also only 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 petrol, when it gets
warmer petrol expands, so buying in
the afternoon or in the
evening....your liter is not exactly a
liter. 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 mode If you look you will see
that the trigger has three (3) stages:
low, middle, and high. You should
be pumping on low mode, 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 Petrol tank is HALF
FULL. 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. 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
petrol truck pumping into the
storage tanks when you stop to buy
Petrol, DO NOT fill up; most likely
the petrol is being stirred up as the
Petrol is being delivered, and you
might pick up some of the dirt that
normally settles on the bottom.
To have an impact, we need to reach
literally millions of Petrol buyers.
It's really simple to do.
