I was scrolling thru my blog notes and found this info about saving money on gas:
Money-Saving Tips for Pumping Your Gas
I don’t know what you may be paying for gasoline but we are paying $3.75 to $4.10 a gallon. At these prices filling up is more than a few dollars, so, here are some tricks to get more for your money:
•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. A one-degree rise in temperature is a big deal. When gasoline gets warmer it expands. Buying in the afternoon or in the evening, after the ground has warmed up, means – your gallon is not exactly a gallon.
•When you’re filling up do not set the trigger of the nozzle to a fast setting. Most triggers have three settings: low, middle, and high. You should pump on low mode, thereby minimizing the amount of vapors that are created while you are pumping. If you pump 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 your gas tank when it is HALF FULL. The reason for this is the more gas you have in your tank the less air is occupying its empty space. Gasoline evaporates faster than you can imagine!
•Also, if there is a gasoline truck pumping into the storage tanks, DO NOT fill up; most likely the gasoline is being stirred up as the gas is being delivered and you might pump in some of the dirt that normally settles on the bottom.
