TIPS ON PUMPING GAS (Good information)

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 f uel, 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. 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.

Hope this will help you get the most value for your money.

interesting article and tips... i always thought it was good to run my car on fumes since there's less weight of the gas to drag around, fortunately I have a civic for a commuter thats giving me 36mpg and around here in we're paying around $3.65 for regular

You guys should just axe my opinion on gasoline related matters.

I mean - I'm a chemical engineer for one of the 3 biggest refineries in the US.

I posted a response to this on another board.
