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 warme r 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. 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 other 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 i mportant tips is to fill up when your gas tank is HALF FULL
or HALF EMPTY. 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.
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. Hope this will help you get the most value
for your money.
