I don’t know what you guys are paying for gasoline…but in California people are paying up to $3.75 to $4.10 per gallon. A gentleman, whose line of work has been in petroleum for about 31 years now, recently offered some tricks to get more of your money’s worth for every gallon.

At the Kinder Morgan Pipeline where he works in San Jose, CA, they deliver about 4 million gallons in a 24-hour period through the pipeline.. One day is diesel the next day is jet fuel, and gasoline, regular and premium grades. They have 34-storage tanks there with a total capacity of 16,800,000 gallons.

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.

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 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 back into the underground storage tank so you’re getting less worth 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. Unlike service stations, every truck that is loaded at the petroleum facilities is temperature compensated so that every gallon is actually the exact amount.

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.
