With Petrol expected to reach $2 per litre by end of 2011, these

tips that I received from a friend might come in handy.


TIPS ON PUMPING PETROL


I don't know what you guys are paying for Petrol.... but

here in Melbourne we are paying up to $1.30 to $1.50 per litre. 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 Shell Pipeline where I work in Melbourne, 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, regular and premium

grades. We have 34-storage tanks here with a total capacity of

16,800,000 Litres.



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 Petrol, 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 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 vapors 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 vapor.

Those vapors 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. Petrololine 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.

He's got a point. I used to workwith Bulk Fuels, when we dipped the tanks each day the amount recorded had to be temperature compensated with a formula I've forgotten.

What a load of bollox

Any savings I would have got due to expansion is gone immediately you put your foot down and boot it up the road

This maybe true for people manic about figures and detail, but in the real world it doesnt mean a thing.

You might want to check the calibration of the petrol pump first

dont you mince your words steven ! lol

Oh and the reason fuel storage facilities have a floating roof is to prevent fuel vapour & air mixing... which is highly explosive.

Petrol in liquid form isnt that explosive at all, it'll quite happily burn away nicely.

You mix it with air though and its massively dangerous

So is sawdust and custard powder dust... I've seen 'controlled' explosions done with sawdust.. holy moly...

Hence why following a petrol tanker towards a refinery I give it a wide berth and double the clearance

I do agree that filling up during colder temperatures does make some difference
Over time 1% makes quite an amount
When receiving tanker deliveries the temperature has to be included, as the received fuel is normally higher than the fuel already in the tank
So 7000 litres in the tanker soon becomes just over 6900 litres, yet we get charged for 7000 litres and this gets passed on to the customer

7000 litres almost sounds like a domestic delivery

When I worked for Esso many many years ago we used to ship out 25,000 litres deliveries all the time.

We had some right stories to tell as well

Like the time our ESSO depot was full of BP Trucks filling up for BP Petrol Stations and the time a wheel sheared off a truck on the motorway and it took 5.5 hours to find it !!! ... and the numerous cross fuelling deliveries and the trouble it causes

Rubbish, the OP is just a copy and paste of an article thats been doing the rounds for years on t'interweb.. Just google

and you'll see that its been modified to suit various countries (Australia, California etc) for ages..

I've heard this before, Clarkson, Top Gear, for one. How does this work, when thousands are spent converting latent heat in the earth to heat homes - Geothermal energy??

Below ten feet the earth's temperature is fairly constant, generally around ~10ºC (~50ºF).
