Hi!
With gas expected to reach $5 per gallon by summer, these tips that I received from a friend might come in handy.

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.

All of this combined is probably good for about another .01 MPG.

I challenge anyone to measure the temperature of gasoline pumped in the morning and in the late afternoon and show a measurable, repeatable difference. Next time you are filling up on a hot summer day look at the metal part of the nozzle. It will be covered with condensation from cold fuel flowing through it.

I think the thing about not filling up when they are filling their tanks is a red herring too. You think those pumps don't have internal filters? Not to mention cars have fuel filters as well.

doesn't mean you want to be replacing fuel filters all the time. good stuff pizza

As far as filling up when they are getting fuel, DO NOT DO IT!!!!!!!!!!!!!

We had a customer years ago fill up his 95 Vette by mistake when we were getting fuel and it cost over 4 k to fix his car! New pump, injectors and clean the COMPLETE fuel system out. He only put in 5/6 gallons at the time.

I've heard that filling up when it's colder out makes almost no difference and sure its a bif difference to the oil companies but they are dealig with things a scales 10,000 times larger at the least than our cars.

of course if you fill your car up at half a tank you are always carrying more weigh and thus getting worse mileage

try it. fill up a 5 gallon gas can on HIGH then fill up the same can on low. i got a noticably difference in can fullness on low. But you morons will just debate shit online i try it.

If you have the pump on full blast it will kick off sooner, because splashing or foaming fuel will trip the automatic shutoff sensor. But will it affect the accuracy of the meter? That technique would allow you to fill the tank higher, but I don't see how you would get more fuel per dollar.

have the pump read 5 gallons. then fill up another can both started with ZERO fuel. and the one you filled up on low has more fuel. the only time i ever cared(it was really maybe 1/8 1/4 inch in diffence in over all height up the "fill gauge". but i made sure i had EXACT 5 gallons wen i mixed my dirt bike 2 stroke gas. i just never realized why it was different. now i know. so go ahead say it makes no difference ive done it.

I never really put that much thought into how to pump gas. I will give a few tips a try. Paying for 93 in all but 2 vehicles... it can't hurt to try, right

i saw this on facebook awhile ago. ima lways to cheap to fill to the top and fill everytime at half a tank so i ignore that one, im too lazy to fill up early in the am im always still sleeping. only one i can use is the "slow pour" which i actually have been doing. dosent really take too much longer and hey if it helps it helps!

Ok, tried it today since I had to fill up a couple gas cans anyhow.
Two identical 5 gallon cans. One slow pump, one fast pump.
Got home, weighed them both on our digital scale. Both weighed 38.4 lbs.
Sorry mike, wanted to prove you right but now I need to disagree based on my scientific testing procedures :p

Both gas cans are of identical design from the same manufacturer bought at the same walmart at the same time.

I'd weigh them for you but they're plastic and I don't think they'll register on my scale lol.

Good Work Captain Asswhipe! maybe new pumps have fixed that issue. it was about 2 years ago wen i was fucking with the bikes so. shit has changed i guess! or im just a lame ass and "figured" it was different cuz some "old timer" told me it was!!!! then i saw the email and i was like CONFIRMED!!!!(mythbusters reference)

hmmmmm maybe it works with like larger quantitied like 20-30gal worth? cuz it is fumes etc. and maybe the different input design of the gas can and a gas tank fille rneck has something to do with it?

Have you guys ever actually tried to pump on slow? I mean holy shit! I used to need to do it with my ford ranger because the filler neck was rusted out. I needed to leave a good 15 minutes earlier for work to get half a tank when it would normally take maybe 2 or 3 minutes. You will fall asleep at the pump with it on slow. And also don't a lot of pumps work on slightly different systems? I mean you can feel the difference from station to station, wouldn't some be more or less efficient then others? Although they are all working on the same principles and I'm sure all need to abide by the same standards, wouldn't they still vary some and affect how much these little ways to "get more in your tank" actually work? Btw one real way to "save" or more of less cheat on gas that I found out by myself. If you look around and try all the different pumps, when the pump stops and you can still feel pressure in the trigger, partially depress it, sometimes the vacuum stop feature on the pump is broken and it will keep dripping into your tank until you release the trigger. I have one pump by my house I do this with, it takes you forever to get more gas but I put on 5 bucks and filled up almost half a tank. It took about 25 minutes but i needed gas and that was all the money I had. Just as an fyi

Ok, tried it today....

Which gas station was it!?!?!?!? I'm not sure about the SPEED of pumping, may or may not have an effect supposedly you just EXPERIMENTALLY proved it wrong, but not scientifically. As far as this goes I'm more interested in the temperature of pumping the gas having an effect. This can be proven experimentally at the pump and scientifically by observing the thermal expansion of gasoline. I'm sure the change in volume would be pretty small being that the temperature change between day and night would be small and the coefficient of thermal expansion of gasoline is pretty low. So in a gas tank I don't think there would be that big of a change, but you would def save money if you did this year round if you wanted to wake up early every day you pump gas. I'll check it out sometime when I finish my chemistry homework early.
