Tips On pumping Petrol

Tip #1

Only buy or fill up your cars or bike in the

early

morning

when the ground temperature is still cold.

Remember

that

all petrol station have their petrol storage

tanks

buries

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 of petrol.

In the petroleum business, the specific gravity

and

the

temperature of the petrol, diesel and jet fuel,

ethanol and

other petroleum product play an important role. A

one

degree

rise in temperature is a big deal for this

petroleum

business. But the petrol station do not have

temperature

compensation at the petrol pumps.

Tip #2

When you are filling up petrol, do not squeeze

the

trigger

of the nozzle to a fast mode. If you look, you

will

see

that the trigger has three stages, low, middle

and

high. In

slow mode, you should be pumping petrol on low

speed,

thereby minimizing the vapours that are created

while

you

are pumping. All hoses at the petrol pump have a

vapour

return. If you are pumping on the fast rate, some

of

the

liquid that goes to your petrol tank becomes

vapour.

Those

vapours are being sucked up and back into the

underground

storage tank so you are getting less worth for

your

money.

Tip #3

One of the most important tips is to fill up

petrol

when

your 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.

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 petrol station, here where I work, every

truck

that

we load is temperature compensated, so that every

litre is

actually the exact amount.

Tip #4

Another reminder, if there is a fuel truck

pumping

into the

petrol storage tanks, then you stop to buy, do

not

fill up.

Most likely the petrol 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 of the petrol

storage

tank.
