TIPS ON PUMPING GAS

I don't know what you guys are paying for
gasoline....Here in California we 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 more of your 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 through the pipeline. One day is
diesel the next day is jet fuel, and gasoline, regular
and premium grades. We have 34-storage tanks here with
a total capacity of 16,800,000 gallons.

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 gasoline, when it gets warmer gasoline
expands, so buying in the afternoon or in t he
evening....your gallon is not exactly a gallon. In the
petroleum business, the specific gravity and the
temperature of the gasoline, 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. In slow mode you should be pumping on low
speed, 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
gas tank is HALF FULL or HALF EMPTY. The reason for
this is, the more gas you have in your tank the less
air occupying its empty space. Gasoline evaporates
faster than you can 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 work, every truck that we load is
temperature compensated so that every gallon is
actually the exact amount.

Another reminder. If there is a gasoline truck pumping
into the storage tanks when you stop to buy gas, DO
NOT fill up--most likely the gasoline is being stirred
up as the gas is being delivered, and you might pick
up some of the dirt that normally settles on the
bottom.

Hope this will help you get the most value for your
money.

i work in the oil and gas industry (engineering) and i have often heard the same thing...

Definately true, you can take a couple of graduated glasses and put in a measured amount of gas in the morning, seal it and then check the level when it's hot.
