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 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 f the dirt
that normally settles on the bottom. Hope this will help
you get the most value for your money.

Yeah he was trying to explain to both negative and positive minded people.

Not to burst anyone's bubble, but that's been circulating around for years. It also started as a chain e-mail letter, too, so I'd take it's legitimacy with several grains of salt...

+1. I saw this a few months ago posted by another member...

Thanks for the info! I've known about filling up in the morning when the ground is colder then the outside air, but I didn't know about the gasoline vapor being a huge deal.. I'll try it and see what happens

As far as temperature is concerned, a change of one degree celsius is about a 0.1 percent change in volume. But then again the ground temperature changes very little over the course of a year much less a single day.

And driving more conservatively also helps.
