TIPS ON
PUMPING GAS

I don't know what you guys are
paying for gasoline.... but here in California we are paying up to $3.75
to $4.10 per gallon. 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. You should be pumping on low mode,
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.

The density difference by the temperature being a few degrees different, would be so minimal it wouldn't even matter. Also the ground is a very good insulator. How far under are the tanks buried? I don't think the tanks will very much difference,if any difference at all.

Wouldn't pumping the fuel and closing the tank up faster create less vapor?

its like jumping into a pool. the bigger the splash the more air you create in the water thus evaporating into the sky. or just slipping in the pool. you move water around to make it evaporate quicker. spreading it. same thing with fuel i guess?

correct me if i'm wrong.

Meh, doesn't matter anyway, the amount of fuel that would evaporate in the fuel tank will be basically nothing anyway.

$4.10 per gallon is $1.08 per litre and you're complaining? LOL! :D

Stupid Americans. In American terms it's over $10.00 a gallon in most places in Europe!!!

Petrol is still cheap in America and it's still cheap in Australia. It SHOULD be around $2.00 a litre for us.

I paid $1.65 for BP Ultimate twice in the last two weeks. Meh. It's what it costs - I don't give a toss.

have to agree with CSP here, it's bloody cheap and all these things wouldn't make a difference anyway.

Agreed. Petrol companies can charge what they want.. so long as I need it (which will probably be for many MANY years to come yet) I'll pay whatever they are asking.
