Save Money on Gas

A friend sent me this and I thought it blog worthy:

I have
been in petroleum pipeline business for about 31 years, currently
working for the Kinder-Morgan Pipeline here in San Jose, CA. 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 fue l (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.
  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
  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 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.)
  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’

  1. Let me add three:5) Ride a motorcycle. You’ll get hybrid-beating mileage, Lamborghini-beating acceleration, children will wave as you pass and attractive young women will ask you for rides. The Lord particularly smiles on items 1 and 3, and how you handle items 2 and 4 helps determine your Current Savedness Quotient.6) Walk. I haven’t driven a car today. I have, however, gone on errands…to the bank, to the store…all on foot. Not a penny spent on gas. No carbon emissions, save those that come from the simple act of breathing.7) Um….I don’t know. But that gets us to seven, which is perfect, so you can fill in the blank yourself.
