“Hack” The Gas Pump and Save Money

Suffering with the prices at the pump? Here are some tips for saving a little coin, thanks to our friend Khairul Efeeza:

Only Buy Gas in the Early Morning

In the early hours, the ground temperature is cold. Service stations have their storage tanks buried below ground. The colder the ground, the denser the fuel, when it gets warmer gasoline expands, technically giving you less per gallon.

The specific gravity and the temperature of gasoline is important. And, given that service stations typically don’t have temperature compensation, you want to optimize your fill-up to give more bang for your buck.

Filling Up Is Like Making Love -- Do It Slowly...

Most of us want to fill-up and go... so we squeeze the nozzle in fast mode. Notice that there are three notches on the nozzle... slow, medium and fast. Slow is better.

Why? Because at lower speeds you minimize the amount of vapor created as the gas shoots through the hose. Take note of the hose... they all have a vapor return mechanism. The faster you pump, the more of the gas that you are paying for goes back into the hose and not into your gas tank.

I had a guy ask... wow, why is it taking you so long to fill up? I explained that to him and he seemed quite surprised!

You remember that Pointer Sisters song about the “slow hand” don’t you?

If you are pumping gas at the fastest rate, you pumping some of that gas into your car and some of it back into the service station’s underground storage tank -- and giving it back to the service station. Pump it slowly and so you’re getting less worth for your money.

Fill Up When Your Tank Is ½ Full

This is important because the more fuel you have in your tank, the less air is occupying the tank. Gasoline evaporates faster than you can imagine. Many cars have an internal floating roof inside the tank that provides zero clearance between the gasoline and the atmosphere (minimizing evaporation).

Avoid Service Stations Receiving Gas

If a big truck is unloading gas into the service station’s tanks... the fuel in the tank is being stirred up... meaning any dirt or residue in the tank rises from the bottom and can potentially get into your vehicle’s fuel system. You want gas that has had time to settle.

Great tips, huh?
