My grandfather used to say that “the easiest way to make a dollar is to not foolishly spend the one you have.” Sage advice. And, after hearing about Floyd Mayweather losing $5,000,000 on his Super Bowl bet, it’s clear to me that far too few respect the money they earn.

While a bit off subject, a friend of mine recently forwarded an article to me about how to save the most money you possibly can when fueling your tank. With gas prices forecasted to reach $5/gallon, I think you’ll appreciate these insider tips from someone who has been in the gasoline business for 30+ years.

Sometimes, I’ll teach you how to monetize your Gifts and, others, how to save the money you have. Check out his tips below.

“I don’t know what you guys are paying for gasoline… but here in California we are paying up to $3.75 to $4.10 per gallon. My line of work is in petroleum for about 31 years now. Here at the Kinder Morgan Pipeline where I work in San Jose, CA we deliver about 4 million gallons in a 24-hour period thru the pipeline. One day is diesel the next day is jet fuel, and gasoline, regular and premium grades. We have 34 storage tanks here with a total capacity of 16,800,000 gallons.

Over the years, I’ve learned some tricks to get more of your money’s worth for every gallon you buy. Check out these tips:

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 one degree rise in temperature is a big deal for this business. But the service stations do not have temperature compensation at the pumps. Therefore, fuel early in the morning.

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 gas 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 there is 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.

4) Another reminder, if there is a gasoline truck pumping into the storage tanks when you stop to buy gas, DO NOT fill up as, 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. This is not good for your car.

To have an impact, I’d love for you to forward this to those you know. These tips are accurate and, if enough people gain awareness, consumers could save literally millions of dollars on their gasoline purchases annually.”
