tHIS WAS SENT TO A FRIEND OF MINE FROM A RELATIVE IN CALIF.
I don't know what you guys are paying for gasoline, but in Calif we are paying up to $3.50 per gallon. I have been in the petroleum business for 31 years now and here are some tricks to get more of your money's worth for every gallon:
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 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 temp is a big deal for this business. But the service stations do not have temp commpensation 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 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. ..The reason is the more gas you have in your tank the less air occupying its empty space. Gas evaporates faster than you can imagine. Gas storage tanks have an internal floating roof. This roof serves a zero clearance between the gas and the atmosphere, so it minimizes the evaporation. Another reminder (Mike has told us this many times) DO NOT fill your tank if the gasoline truck is pumping into the storage tanks. The gas is being stirred up and you might pick up some of the dirt that normally settles on the bottom. Hope this will help you get the most value out of your money.
