Tricks to get your money's worth
TIPS ON PUMPING GAS--GOOD INFO
I don't know what you guys are paying for gasoline....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 w here 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 mor e 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 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 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 an d 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.
Hope this will help you get the most value for your money.

I'd really like to take a look at documentation that supports this note.

Even if it is 2 cents cheaper a galon that is .50
And I know the stations that are sometimes as much as .20 cheaper than the other stations. Thats a savings of 2.50 per fillup[:)]
The best advice for the gas pump is stop at the pump with the cheapest price[:D]

yes, but it depend, i've seen several old timers spend 2 gallons of gas to travel to the cheaper stations

Somehow I don't see spending an extra 5 minutes slowly pumping gas so as to save a teaspoon worth of vaporized fuel. Even at $100 a fill for my tank, the minutes are worth more than the teaspoons.
you could look at it 2 ways
fast pumping causes allot of turbulence creating vapor, {btw not all states have a vapor return, it is a real p.i.a}, but it gets it into the tank faster where there is a vent
pumping slow could allow the vapors to release into the atmosphere because of the amount of time it will allow the gas to go down the hose to your tank

I hadn't considered the fast vs. slow pumping option, but I can attest that driving on the top half of the tank will produce a measurable increase in fuel mileage.
i does appear that way, but the truth is the gauge in your dash is not tailored to your particular gas tank capacity, the same gauge may go into several cars with tanks ranging from -18 gallons to 27+ gallon tanks, when it reaches the F it really may be from 60-75% full, so you may have 25-40% more gas in your tank than the gauge can actually read, that's why it sits on F for such a long time
I don't measure my mileage by the reading on the fuel gauge.
so what does that mean, you get better gas mileage from the first ten gallons then the last ten gallons {btw no one does it by the gauge if their doing it right}
