Subject: Tips for fuel

Hi, here's some petrol saving tips.

Someone who has been in petroleum pipeline business for about 31 years and
is currently working for the Kinder-Morgan Pipeline in San Jose, CA wrote
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.


   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-compensated 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.

   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.

   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 rapidly, 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.)

   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'!
