Tips on Pumping Gas

*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. *

Mostly myths..

or, if they are somewhat true, the "savings" are minuscule:

You can save much more money on gas just by checking your tire pressure!

(better gas mileage) and by keeping you car well tuned and maintained.

I would think that the ground temps wouldn't change that much over night to make that much difference too. I do not know how far down they put them tanks but they hold more gas than my swimming pool would and that doesn,t change a whole lot at night ( well ok maybe 5 degrees but thats out in the air where it changes dramatically overnight ).. When you get down into the earth a ways temps just do not change too much..

Anyone ever heard of running water pipes down into the earth to heat/cool a house..It will heat in the cold weather and cool it in the summer..

myth or not

if you are worried about the velocity of vapors in the the recycling tube of a gas pump as your filling up a pickup getting 15 miles to a gallon, driving 100 mile round trip to work - at 75 mph + driving speeds ...

well, I have some compact fluorescent headlights I'd like to sell you for your truck.

god bless

Chuck how much you got to get for those lights? Ill fill up my fuel drinking x state crown vic and drive there to get them.................. :thumbs:

just remember to turn them on about 15 minutes before sunset to let them warm up !

I know that if you just slow down your driving habits, such as, hard accelerating or driving over the speed limit. This will give you better mileage.

Hence my wife thinks I drive like a grandpa and ******* I drive to slow. I can get 28mpg out of her car all the time. But when she drives look out nascar, but she'll get 25mpg or even less.

I am curious. How cold do you all think gasoline would have to be to not vaporize? I know liquid nitrogen boils at -30 degrees. I think liquid propane is very close to that. If the average ground temp below the frost line is around 60 degrees then wouldn't gasoline always make vapor regardless of the air temp? Chuck, could you ship some of those lights to me? I can't afford the gas to come and get them. Oh yeah, send some of them cookies too :thumbs:
