These handy tips were forwarded to me in an email and I thought I would share. In this day and age of high gas prices, every little bit helps.
I don't know what you guys are paying for gasoline.... but here in Georgia we are paying up to $3.40 to $3.99
per gallon. So 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 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 that 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 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 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.
