Got this e-mail today at work. These are some good tips,,,,,,,,,,,,

For all of you that hate gas prices. This is good information.

New Gas Tips

I don't know what you guys are paying for gasoline....Here in
California we are also paying higher, up to $3.50 per gal.. 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 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 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.
