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.
1. 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 buy ing 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.
2. 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
r ate, 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
wort h for your money.
3. 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.
NOW DON'T THAT MAKE YOUR DAY!
