Petrol Saving Tips
With my previous post on when is the best time to fuel your vechicle, i received an email today on petrol saving tips, the tips is really useful and i will share it out. Let’s starts save our energy and money together…
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’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 we 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.
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.
3. Fill up when your gas tank is
half-full (or half-empty), because 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.)
4. If you look at the trigger you’ll see
that it has three delivery settings: slow, medium and high. When you’re
filling up do not squeeze the trigger of the nozzle to the high setting.
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.
this is crap. you should also only fill your tank when the sun is directly overhead, because the gravity of the sun will pull on the gas and make it easier to pull up from the tank.

Tip 5.
Remove the engine, punch 2 holes in the floor of your vehicle and do a Fred Flintstone.

jd the pump does not mass the gasoline if measures it as it pumps it. The more dense it is when you pump it the more you get. It will always expand a bit once it gets into your tank. The only way your theory would work would be if the sun made a huge difference in gravity based on what side of the planet you are on, which it does not.

dj you are wrong the article is right. The only ways your theory would work would be if the sun pulled significantly harder on the close side (the lighted side) of the earth than the far side (the dark side), which it does not. That and it doesn’t measure how ling it takes to pump it it measures how much volume passes through the pump, which is why you should fill up in the morning because the gas is more dense than in the afternoon or evening.

JD, if you are serious, you are an absolute moron.
Everyone knows the moon should be overhead, not the sun. LOL

I’d love to see a scientist try this and see if his theories are correct. if true by outside witnesses it would be a good money saver for the average paying customer!
