Here are some tricks to get more of your money’s worth for

every gallon.This information was shared by someone who has

worked at the Kinder Morgan Pipeline in San Jose, CA for

about 31 years. 

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.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 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 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.

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. Hope this will help you get the most

value for your money.
