Saving Money at the Gas Pump

Buying Gas The Smart Way: Tips on Pumping Gas

I’m not sure what everyone is paying for gasoline these days, but here in Florida it ranges from about $3.30 to & 4.00 per gallon at the time of writing this. While doing some reading I came across these tips from a Petroleum insider who has worked in the industry for 31 years. Here are his tips for getting the most you can with every fill up.

1. 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. Unlike service stations, every truck that they load is temperature compensated so that every gallon is actually the exact amount.

Gas Saving Tips

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) 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 put back into the underground storage tank so you’re getting less product for your money.


3. 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.


4. 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.


We hope that you take the time and share this with your family and friends. If we can get the message out to more people, then we all can save a little at the pump.
