Folks. Here's a great little read on getting the most out of the pump at the station.
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. B ut 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 s till 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 b usiness. 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 hose s 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 s ucked 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 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 r eminder, if there is a gasoline truck pumping into the storage
> tanks when you stop to buy gas, DO NOT fill up--most likely the g
> asoline is being stirred up as the gas is being delivered, and you
> might pick up some f the dirt that normally settles on the bottom. Hope
> this will help you get the most value for your money.

> Gas rationing in the 80's worked even though we grumbled about it. It

> 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 the Saudis.
