A friend of mine had sent me this a while back and thought I would share it.

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.

To have an impact, we need to reach literally millions of gas
buyers. It's really simple to do.

Good tips, but still too costly.. I get my gas by siphoning my neighbors car... Cost FREE :hello2:

Maybe I should start on post on the best ways to siphon, I got a million of em :laughing9:

You just ain't right, Spartacus! LOL!! :laughing7:

We call 'em (siphon hoses) Georgia Credit Cards here in East Tennessee! LOL!! :laughing9:

Sad part about it is when fuel was going up a couple of years ago people would find their fuel tanks, (being plastic), thieves would drill a hole in the botton of the gas tank and fill the gas cans especially on trucks being they sit higher off the ground!

I'd say it's that way big time in the city, Harley.

Living where I do, you know who's outside by the way the dogs bark.

Underground temps are remarkably constant, so this tip, at least, is bogus.

The whole thing started out a bit too fishy for me with the assertion that a guy who worked at a pipeline would write this. I highly doubt that.

One must also consider the fact that cool mornings would still have an effect on the temperature of the fuel tank in the vehicle you drive and I'm

sure no one would argue with the fact that cooler fuel is denser fuel. That's why when we take fuel on in an aircraft, we measure it by the pound.

Out of curiosity: Do you think underground tanks are deep enough to maintain a steady temperature? (I know caves around here in Tn. stay about 58 degrees Fahrenheit year round).


Thanks all!

He gives you some bogus advice (the writer, not the poster) that sounds good, but if you follow it, you could be wasting gasoline if you fill up.

Yes, the fuel is more condensed in the morning. However, if you fill up just before you get to work, you will find that by the time you get off at the end of a warm day, that there is a strong gasoline smell around your vehicle. Why? Because heat later in the day will expand it.

If you fill the tank and only drive a couple miles, the fuel in the tank WILL expand, but as we know, if the tank is full the only place for it to go is out into the atmosphere through the "overflow" hose. That is why the old cars used to actually leak gas from the gas cap on a hot day.
