Tips on pumping gas

Saw this on Facebook and thought i would share here..

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.
I'm sending this note to about thirty people. If each of you send it to at least ten more (30 x 10 = 300)...and those 300 send it to at least ten more (300 x 10 = 3,000) and so on, by the time the message reaches the sixth generation of people, we will have reached over THREE MILLION consumers !!!!!!! If those three million get excited and pass this on to ten friends each, then 30 million people will have been contacted!
If It goes one level further, you guessed it..... THREE HUNDRED MILLION PEOPLE!!!
Again, all you have to do is send this to 10 people. How long would it take?

I saw that as well. Some of the things it talked about made sense, like buying in the AM because the gasoline is more dense. But until some one gives me some numbers I'm bit sure how much of a difference it would make.

The only true fact there is the part about not filling up when the truck is filling up the stations tanks. My dad made that mistake once and had to pull his gas tank plug and drain the tank because the gas was so contaminated that the engine wouldn't run. No one in my family has ever filled up again while the delivery truck is there.

Isn't a gallon; a gallon? No matter if it is 50* or 90*? Kind of like which weights more; a pound of lead or a pound of feathers...a pound is a pound. I work in the chemical industry too, and we don't change any calibration on any flow meter because of the temp change. Here in Houston, we can see temps from low 30's up to 110, so I'm going to call BS on that. Just my 2 cents.

I came here hoping that someone else had a problem with the tank spitting gas back at them when they fill up.......

That just reeked of chain e-mail to me, no hard feelings. I do avoid filling up when there's a truck filling the station tanks, though my reasoning is because it gets in the way and makes it a hassle.

My gas pumping tip is to always pull your lifted Jeep next to a Hummer when the opportunity arises. The jealous looks you get can really turn a bad day around.

That's your first problem. 99% of the shared crap on Facebook is full of fail. The new thing now is "I'm trying to find my birth parents."

Read this to understand why.

I've avoided responding to this on Facebook cus I don't want to have to deal with the 1000000 people that either will ignore it or, even worse, will respond to it.

The tips are all true, but following them wont save you more than a few cents. It's true, when you're dealing with millions of gallons a day, the density of the product matters quite a bit... when you're filling up your 16 gallon tank, not so much. And, as someone already mentioned the ground temperature is quite consistent, even in the heat of the late afternoon. If you touch an oil pipeline as it comes out of the ground, it is chilled, even if you're hanging out in 100 degree midwest weather.

Again, the tip regarding the vapor recovery is true, in that you do have some of your precious fumes exhausted (and that is in your best interest). And, again, its not enough for you to care Increased flow rate might increase the surface agitation in your tank, and thus increase evaporation, but that doesn't much matter either.

Filling up when a truck is unloading.... ok thats a bit legit, especially if you are out in podunk no where filling up. A high volume station will have more turnover, and less particulates/gunk/whatever will build up in their tanks. Lower volume sites will definitely have their tank bottoms disturbed as the trucks offload...

Here's some real truth about gasoline: http://www.api.org/oil-and-natural-g...e-Tax-Map.ashx

Check out how much you pay on fuel taxes in your state I was definitely shocked when I first saw this. I'm glad I'm in one of the blue states (with regard to the map... hah).

Send this to 300 of your friends and you will find a golden bunny playing the solo to stairway to heaven... or don't. Either way, I like talking about this kind of stuff, and doing my best to bring awareness to those outside the industry (even if I did just ramble on a bit). Hope this helps, if not... ask questions!

Spam, yeah, but he was just trying to help. Facebook is evil. I'm tired of having friends of mine show up on my newsfeed because they like'd an article claiming they would get a Playstation 12 or something.

Every dispenser has a filter for both grades of fuel (regular and premium, mid grade is a mix of the two and happens right inside the dispenser cabinet) so buying fuel during or after a tanker drop won't cause any more sediment/ particulate to enter your tank.

Exactly. Most of that shit posted is theory. Here's the gas station I'm building right now
