on Pumping Gas From a Pipeline Employee-Fiction!
Summary of the eRumor: A list of tips about how to pump gas most
efficiently so that you can save fuel costs. Tips such as getting gas in the
morning and filling the tank when it is still half full. The writer
of the email says he's an employee of the Kinder Morgan Pipeline in San
The Truth: A spokesperson for the Kinder Morgan companies
in Houston, Texas, told TruthOrFiction.com that as far as he knows this
email did not originate from a Kinder Morgan employee. He added that
although it is true that temperature and pressure affect the volume of
liquids and gases, the impact on the average vehicle gas tank is so small
that the advice in this eRumor is of little value. Most storage
tanks at gas stations are so deeply underground and some of them insulated
or double-insulated, that the temperatures of the fuel in them do not
fluctuate very much.
A real example of the eRumor as it has

TIPS ON PUMPING GAS--GOOD INFO!
I don't know what you guys are paying for gasoline....Here in
are also paying higher, up to $3.50 per gallon. But my line of
work is in
petroleum for about 31 years now, so here are some tricks to get
money's worth for every gallon.
Here at the Kinder Morgan Pipeline where I work in San Jose, CA we
deliver about 4
million gallons in a 24-hour period thru the pipeline. One
the next day is jet fuel, and gasoline, regular and premium
34-storage tanks here with a total capacity of 16,800,000
Only buy or fill up your car or truck in the early morning when the
temperature is still cold. Remember that all service stations have
tanks buried below ground. The colder the ground the more
gasoline, when it gets warmer gasoline expands, so buying in
or in the evening....your gallon is not exactly a gallon.
In the petroleum business, the specific gravity and the temperature

this business. But
the service stations do not have temperature compensation at the
When you're filling up do not squeeze the trigger of the nozzle to
a fastmode. If
you look you will see that the trigger has three (3)
middle, and high. In slow mode you should be pumping on low speed,
minimizing the vapors that are created while you are pumping. All
pump have a vapor return. If you are pumping on the fast rate,
liquid that goes to your tank becomes vapor. Those vapors
sucked up and back into the underground storage tank so you're
worth for your money.
One of the most important tips is to fill up when your gas tank is
HALF EMPTY. The reason for this is, the more gas you have in
less air occupying its empty space. Gasoline evaporates faster
imagine. Gasoline storage tanks have an internal floating roof.
This roof serves as zero clearance between the gas and the
atmosphere, so it
minimizes the evaporation. Unlike service stations, here where I

Another reminder. If there is a gasoline truck pumping into the
when you stop to buy gas, DO NOT fill up--most likely the
being stirred up as the gas is being delivered, and you might pick
up someof the
dirt that normally settles on the bottom.
Hope this will help you get the most value for your money.
