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 store their fuel in underground tanks, and the temperature of the ground affects the density of the gasoline. Colder ground temperatures make gasoline denser, while warmer temperatures cause it to expand. As a result, when you fill up in the afternoon or evening, the amount you pump may not be a full gallon due to this expansion.

In the petroleum industry, the specific gravity and temperature of fuel (including gasoline, diesel, jet fuel, ethanol, and other petroleum products) are crucial factors. Each truckload of fuel is temperature-compensated to ensure that the indicated volume is the actual amount being delivered. Even a one-degree rise in temperature is significant for businesses. However, service station pumps do not have temperature compensation, meaning the volume you receive can vary based on the temperature.

Do not buy gas when a tanker truck is putting gas in the station’s gas tanks.

Dirt and sludge in the storage tank likely get stirred up when gas is being delivered, and this debris could end up being transferred from 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, which helps reduce evaporation—especially in warm weather. Gasoline evaporates quickly, so minimizing the amount of air in your tank can help preserve it. (Gasoline storage tanks have an internal floating ‘roof’ membrane that acts as a barrier between the gas and the atmosphere, reducing evaporation.) 

Always pump at the slow setting when filling up 

When you look at the nozzle trigger, you'll notice it has three delivery settings: slow, medium, and high. Avoid squeezing the trigger to the high setting. Instead, pump at the slow setting to minimize the vapors created while fueling. The hoses at the pump are corrugated, with the corrugations acting as a return path for vapor recovery from gas that has already been metered. If you pump fuel at the high setting, the agitated gasoline produces more vapor, which is then sucked back into the underground tank, meaning you're getting less gas for your money.
