Tips on savings at the gas pump

I was sent this today by a petroleum producing client who owns gas stations, you might find it useful.

TIPS ON PUMPING GAS


_ Fill up your car or truck in the early morning when the ground temperature is still cold.
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 one-degree rise in temperature is a big deal. 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. 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 fuel 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 rapidly. 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. The tank on your vehicle does not.
_ 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.

It's a generic e-mail that's been floating around since Oct.

Here's the take on it from Snope.com:

I've noticed that the price of gas is changed in the late morning or early afternoon, so depending on your area, it might be wise to fill up early in the morning before the price goes up for the day.

I owned a 7-11 Store for 14 years with Gas pumps: Orange CA

I agree completely with how to pump gas that has been posted. Most of us in the industry know that what was posted in this post is correct.

The reason that the price is increased in late morning or early aftenoon is because this is the time the "Field Rep" comes by the gasoline station and has the keys to change the price because the owner of a 7-11- AM PM /etc doesn't have the keys to change the price.
