HOW TO SAVE MONEY WHEN BUYING GASOLINEAre you sick and tired of paying too much money for gasoline? These tips are
GUARANTEED to save you money when you fill up.
1. Only buy gasoline or fill up your vehicle in the early morning hours when the ground
temperature is still cold. Remember, 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 greatly, so buying in the afternoon or evening, ...your gallon is
not exactly a whole, liquid gallon. In the petroleum business, the specific gravity and the
temperature of the gasoline, diesel, jet fuel, ethanol and other petroleum products
plays an extremely important role. A 1-degree rise in the temperature is a big deal for
this business. But the service stations do not have temperature compensation at the
pumps, hence, you are paying for air ( vapors ) and not all liquid gasoline.
2. 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) settings: low, middle and high. In the
low mode ( the slowest pumping rate ), you should be pumping on low speed, thereby
minimizing the amount of vapors that are being created while you are pumping. All hoses
at the pump have a vapor return. If you are pumping on the high “fast” mode, 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 liquid gasoline for your
money.
3. 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 that is
occupying its space. Gasoline evaporates at an extremely high rate, faster than you can
imagine. Large 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.
4. If there is a gasoline truck pumping into the storage tanks when you stop to buy gas, DO
NOT fill up !! Because the gasoline is being pumped into the storage tanks at a high
rate, the gasoline that is already in the storage tanks is being stirred up as the gas is
being delivered in to them, and you might pick up some of the debris that normally settles
on the bottom.
5. The gasoline pumps are designed to measure the products dispensed by volume and not by
weight. The amount of gasoline and other petroleum products that you just purchased,
isn’t really the amount that you paid for. You paid for the vapors; as well as, the liquids.
This is the amount that registers on the dispenser. So, start filling your tanks at a
much slower rate to get your entire dollar amount of a liquid gallon.
Hope this helps. Now, go forth and save money!
