*With Petrol expected to reach $2 per litre by end of 2011, these tips that
I received from a friend might come in handy.


*I don't know what you guys are paying for Petrololine.... 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 Petrololine, 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
Petrololine, when it gets warmer Petrololine expands, **so buying in the
afternoon or in the evening....your gallon is not exactly a gallon.** In the
petroleum business, the specific gravity and the temperature of the
Petrololine, 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. Petrololine 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 Petrololine truck pumping into the storage
tanks when you stop to buy Petrol, DO NOT fill up; most likely the
Petrololine 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.*
