TIPS ON PUMPING GAS

• The oil industry has known for 100 years that gasoline expands with temperature.
As it warms, gasoline expands by volume but not by weight or
energy content. Since the 1920's, the oil industry has taken temperature
into account for wholesale transactions, and use a 60 degree Fahrenheit standard
when measuring gasoline at wholesale. But the oil industry does not adjust
for temperature in retail sales to consumers. As a result, consumers pay a
Hot Fuel Premium when gasoline temperatures exceed 60 degrees, as they do
during the summer.
• 513.8 million gallons of gasoline sold in the summer 2007 will be
attributable
to the thermal expansion of gasoline.
• Consumers will pay a hot fuel premium of about $1.5 billion in the summer
2007.

Tricks to get your money's worth

TIPS ON PUMPING GAS--GOOD INFO
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 thru 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 the 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. I f 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.
