Gas (Petrol) Tips

Someone who has been in petroleum
pipelin e business for about 31 years
and is currently working for the Kinder-
Morgan Pipeline in San Jose, CAwrote
the following information:

We deliver about 4 million gallons in a
24-hour period from the pipe line;
one day it's diesel, the next day it's
jet fuel and gasoline. We have 34
storage tanks here with a total
capacity of 16,800,000 gallons. Here
are some tricks to help you get your
money's worth.

1. Fill up your car or truck in the
morning when the temperature is still
cool. Remember that all service
stations have their storage tanks
buried below ground; and the colder the
ground, the denser the gasoline. When
it gets warmer gasoline expands, so if
you're filling up in the afternoon or
in the evening, what should be a gallon
is not exactly a gallon. In the
petroleum business, the specific
gravity and temperature of the fuel
(gasoline, diesel, jet fuel, ethanol
and other petroleum products) are
significant. Every truckload that we
load is temperature-compensa ted so
that the indicated gallonage is
actually the amount pumped. A one-
degree rise in temperature is a big
deal for businesses, but service
stations don't have temperature
compensation at their pumps.

2. If a tanker truck is filling the
station's tank at the time you want to
buy gas, do not fill up; most likely
dirt and sludge in the tank is being
stirred up when gas is being delivered,
and you might be transferring that
dirt from the bottom of their tank into
your car's tank.

3. Fill up when your gas tank is half-
full (or half-empty), because the
more gas you have in your tank the less
air there is and gasoline evaporates
rapidl y, especially when it's warm.
(Gasoline storage tanks have an
internal floating 'roof' membrane to
act as a barrier between the gas and
the atmosphere, thereby minimizing
evaporation.)

4. If you look at the trigger you'll
see that it has three delivery
settings : slow, medium and high. When
you're filling up do not squeeze the
trigger of the nozzle to the high
setting.
You should be pumping at the SLOW
setting, thereby minimizing vapors
created while you are pumping. Hoses at
the pump are corrugated; the
corrugations act as a return path for
vapor recovery from gas that already
has been metered. If you are pumping at
the high setting, the agitated
gasoline contains more vapor, which is
being sucked back into the
underground tank, so you're getting
less gas for your money.

Hope this will help ease your 'pain at
the pump'!
