V-Tip: Saving Petrol

(Feeling a little cranky - Sleep Less Nights *been saying that a lot for the whole week*)

From the NEWS:
SOUTH WESTERN EASTERN OF DORKSTINGTON, November 16, 2007: A deranged man in his mid forties was causing a ruckus at the neighbourhood's petrol kiosk when he threatened to shoot a customer with the nozzle after he realised that the price of petrol had risen again. He later tore the clothes he had worn, and went off running nude before the police settled the commotion.

However, it was known that he escaped from the grips of the police, and fled into the woods nearby. If you happen to see a naked man running freely in your neighbourhood, please call immediately this toll free number: 1-600-800-12155. Becareful! He shows no mercy!

Ok, Drinking Saving Petrol...

Guidelines to Petrol Saving #1:
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 are 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 loaded 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 do not have temperature compensation at their pumps.

GtPS #2:
If a tanker truck is filling the station's tank at the time you want to buy gas, do not fill up.

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.


GtPS #3:
Fill up when your gas tank is half-full (or half-empty).

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

GtPS #4:
When you're filling up do not squeeze the trigger of the nozzle to the high setting.

If you look at the trigger you will see that it has three delivery settings: slow, medium and high. You should be pumping at the slow setting, thereby minimizing vapors created while you are pumping. 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.
