Pumping Gas - 4 Tips To Save Gas and Money

With gas prices being at all-time high prices, it is important to know how to make the money you pay for gas to reach as far as it can. There are several ways to make sure you are getting all that you pay for at the pump. These tips are common knowledge to employees of pipe line companies. Make a few adjustments and you'll save gas and get more for your money at the pump.

1. Fill up with gas when it is cool outside. The best time to get gas is in the morning when it is cooler outside. Service stations store their fuel tanks below ground. If the ground is cooler the gasoline will be more dense. Heat causes gas to expand, so if you are getting gas when it is hot outside then you may not be receiving a complete gallon, even though the pump indicates a gallon. The specific gravity and temperature of fuel is very significant. This includes diesel, gasoline, ethanol, jet fuel, and other petroleum products. Each truckload of fuel is temperature-compensated. This is done so that the indicated gallon gage is actually the amount pumped. Even the slightest rise in temperature makes a big difference for businesses. The problem is that service stations don't have temperature compensation at their pumps. That's why the outside temperature can make a difference in how much fuel you get.

2. Don't buy gas if a tank truck is filling the station's tank at that time. We have all seen the big tank truck in the parking lot at one time or another. When these tank trucks deliver the gas sludge and dirt is being stirred up in the tank. So, if you are filling up at the time you might be putting some of that dirt into your vehicle's tank.

3. Don't wait until "empty" to fill up. The best time to fill up is when or gas tank is half empty. The more gas you have in your tank the less air there is in your tank. Gasoline evaporates fast, and it will evaporate even more rapidly when it is warm. Gas tanks are equipped with an internal floating roof membrane to serve as a barrier between the atmosphere and the gas. This minimizes evaporation, so you'll want to fill up more often.

4. Pump gas on the "slow" setting. Usually, the trigger on the fuel pump will have a fast, medium, and slow delivery option. You need to use the slow setting. Using the slow setting will reduce the vapors created in the process of pumping. The hoses at fuel pumps are corrugated. These corrugations act as a return path for vapor recovery from gas that already has been metered. At the fast pumping setting, the agitated gas contains more vapor. This vapor is sucked back underground into the tank, and this causes you to receive less gas than what the pump indicates.
