TIPS ON PUMPING GAS
I don't know what you guys are paying for gasoline.... 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.

People believe what their Tv tells them as well.

I wonder what the true cost is by not following these tips? What amount does the station recover? Interesting stuff here.

Facebook?

Pretty sure my old man got this same piece of information, word-for-word, from a fax machine distribution list when he got his first business fax machine in the '80s.

At the rate I seem to burn gasoline, it spends little time evaporating I can't help it, "if it does not burn fossil fuel, I don't like it".

That's a myth. The temperature of the ground just a few feet below the surface is a pretty constant 50-60°F year round in temperate climates. The difference from morning to afternoon is minimal.

That may have been true 50 years ago, but any gas station today is going to have filters between the tanks and the dispenser.

Agreed, the temperature doesn't change much, even my basement stays within 5-6 degrees winter to summer. More important will be the temperature of the fuel in the tanker fleet, and how long ago the underground tank was filled.

Yes I've seen the filters, We had them on our pumps. I have never seen anyone change them, and I don't know if they have a bypass or not. But I have seen diesel filters on cars getting saturated very quickly, often within minutes after getting fuel

The OP has posted a copy/paste of a long-known (at best, partially true) series of "tips" which has been floating around the internet for a long time.
