Good information and makes sense. Pass it on!

I've 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 pipeline; one day
it is diesel, the next day it's jet fuel and gasoline. We have 34
storage tanks here with a capacity of 16,800,000 gallons. Here are some
tricks to help you get your money's worth:
1) Fill up your car/truck in the morning when the temperature is still
cool. Remember that all service stations have their storage tanks
buried below ground. The colder the ground the denser the gasoline.
When it gets warmer gasoline expands, so if you're filling upin the
afternoon or evening, what should be a gallon is not exactly a gallon.
In the petroleum business, the specific gravity and temperature of the
fuel (gasoline, jet fuel, diesel, 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. (ed.: Which means "too bad for us"........)
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 are 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 because the more gas you
have in you 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. (ed.: Another reason not to
wait until you are empty is that you are gradually burning out the fuel
sender unit in your gas tank. The fuel pump/sender unit is all one part
on most cars now..........replacement is roughly $600)
4) If you look at the gas trigger (at the pump) 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.
