Fueling Tips to Save You Money

Fill up your car or truck in the morning when the temperature is still cool

Remember that all service stations have their storage tanks buried below ground; and the colder the ground, the denser the gasoline.  When it gets warmer gasoline expands, so if you’re filling up in the afternoon or in the evening, what should be a gallon is not exactly a gallon.  In the petroleum business, the specific gravity and temperature of the fuel (gasoline, diesel, jet fuel, ethanol, and other petroleum products) are significant.  Every truckload that they load is temperature-compensated so that the indicated gallonage is actually the amount pumped.  A one-degree rise in temperature is a big deal for businesses, but service stations don’t have temperature compensation at their pumps.


Do not buy gas when a tanker truck is filling the station’s gas tanks

Most likely dirt and sludge in the tank is being stirred up when gas is being delivered, and you might be transferring that dirt from the bottom of their tank into your car’s tank.


Fill up when your gas tank is half-full or half-empty

The more gas you have in your tank the less air there is and gasoline evaporates rapidly, especially when it’s warm.  (Gasoline storage tanks have an internal floating ‘roof’ membrane to act as a barrier between the gas and the atmosphere, thereby minimizing evaporation.)


Always pump at the slow setting when filling up 

When you look at the nozzle trigger you’ll see that it has three delivery settings: slow, medium and high.  Do not squeeze the trigger of the nozzle to the high setting. You should pump at the slow setting, thereby minimizing vapors created while you are pumping fuel.  The hoses at the pump are corrugated; the corrugations act as a return path for vapor recovery from gas that already has been metered.  If you are pumping at the high setting, the agitated gasoline contains more vapor, which is being sucked back into the underground tank so you’re getting less gas for your money.
