Kind of Weird But Interesting

>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 
>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
