TIPS ON PUMPING OUR EXPENSIVE GASOLINE

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 buying
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. 

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.  You should be pumping on low mode,
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 rate, 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 worth for your money. 

One of the most important tips is to fill up when your gas tank
is HALF FULL.  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. 

To have an impact, we need to reach literally millions of gas
buyers.  It's really simple to do. 

I'm sending this note to about thirty people. If each of you
send it to at least ten more (30 x 10 = 300)...and those 300 send it to
at least ten more (300 x 10 = 3,000) and so on, by the time the message
reaches the sixth generation of people, we will have reached over THREE
MILLION consumers !!!!!!!  If those three million get excited and pass
this on to ten friends each, then 30 million people will have been
contacted! 

If It goes one level further, you guessed it..... THREE HUNDRED
MILLION PEOPLE!!!
