If you are interested in lowering our dependence on Middle East Oil and getting the most gas in your tank for the least amount of money every time you fill up, read this post from beginning to end.
TIPS ON PUMPING GAS

I don't know what you guys are paying for gasoline.... but here in
California we are also paying higher, up to $3.50 per gallon. But my
line of work is in petroleum for about 31 years now, so here are some
tricks to get more of your money's worth for every gallon..
 
Here at the Kinder Morgan Pipeline where I work in San Jose , CA we
deliver about 4 million gallons in a 24-hour period thru the pipeline.
One day is diesel the next day is jet fuel, and gasoline, regular and
premium grades. We have 34-storage tanks here with a total capacity of
16,800,000 gallons.
 
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. In slow mode you should be pumping on
low speed, 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 other 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 or HALF EMPTY. 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 atm osphere, 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.
Hope this will help you get the most value for your money.
 
DO SH ARE THESE TIPS WITH OTHERS!
 
WHERE TO BUY USA GAS, THIS IS VERY IMPORTANT TO KNOW. READ ON

Gas rationing in the 80's worked even though we grumbled about it. It
migh t even be good for us! The Saudis are boycotting American goods. We
should return the favor!

An interesting thought is to boycott their GAS.

Every time you fill up the car, you can avoid putting more money into
the coffers of Saudi Arabia . Just buy from gas companies that don't
import their oil from the Saudis.
 
Nothing is more frustrating than the feeling that every time I fill-up
the tank, I am sending my money to people who are trying to kill me, my
family, and my friends.
 
I thought it might be interesting for you to know which oil companies
are the best to buy gas from and which major companies import Middle
East ern oil.
 
These companies import Middle Eastern oil:

Shell........................... 205,742,000 barrels
Chevron/Texaco......... 144,332,000 barrels
Exxon /Mobil............... 130,082,000 barrels
Marathon/Speedway... 117,740,000 barrels
Amoco ............................62,231,000 barrels

Citgo gas is from South America , from a Dictator who hates Americans.
If you do the math at $30/barrel, these imports amount to over $18
BILLION! (oil is now $100+ a barrel)
 
Here are some large companies that DO NOT import Middle Eastern oil:

Sunoco................0 barrels
Conoco................0 barrels
Sinclair.................0 barrels B P/Phillips...........0 barrels
Hess.....................0 barrels
ARC0....................0 barrels

If you go to Sunoco. com, you will get a list of the station locations
near you.
 
All of this information is available from the Department of Energy and
each is required to state where they get their oil and how much they
are importing.
 
But to have an impact, we need to reach literally millions of gas
buyers. It's really simple to do.

Now, don't wimp out at this point.... keep reading and I'll explain how
simple it is to reach millions of people!!
 
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) .. an d so on, by the time the message
reache s 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!!! Again, all you have to do is send this to 10 people.
