Tips To Save At The Pumps...

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 ge ts 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 pumps.

When you're filling up do not squeeze the trigger of the nozzle to a fast
mode . If you look you will see t hat the trigger has three (3) stages:
low, middle, and high. In slow mode you should be pumping on low speed ,
thereby m inimizing 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 g etting 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 wh en 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
