This is really interesting................. I received this e-mail today and want to pass it on. With the 

of gasoline, we can all use help saving!!!!

"I don't know what you guys are paying for gasoline.... 

Here in California we are also paying higher, up to $3.50 per gallon. But 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 

t

 he 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. In slow mode you should be pumping on low speed, 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 or 

HALF EMPTY.  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 pum

 ping 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. 

Hope this will

  help you get the most value for your money."

I am going to follow the above advice and see if I save anything!
