TIPS ON PUMPING GAS
*Only buy or fill up your car or truck in the early morning. 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 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 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.
Hope this will help you get the most value for your money
