    Oil guys - is there any truth to this, I think so, but minimal.

    Tips on Filling your Vehicles...

    >I don't know what you guys are paying for petrol... but here in Durban, we

    >
    >Here at the Marian Hill Pipeline, where I work in Durban, we deliver about

    >
    >One day is diesel; the next day is jet fuel, and petrol, LRP and Unleaded.
    >We have 34-storage tanks here with a total capacity of 16,800,000 litres.
    >
    >ONLY BUY OR FILL UP YOUR CAR OR BIKKIE IN THE EARLY MORNING WHEN THE
    >GROUND TEMPERATURE IS STILL COLD. Remember that all service stations have
    >their storage tanks buried below ground. The colder the ground, the denser
    >the fuel, when it gets warmer petrol expands, so buying in the afternoon
    >or in the evening.... your litre is not exactly a litre.
    >
    >In the petroleum business, the specific gravity and the temperature of the
    >petrol, diesel and jet fuel, ethanol and other petroleum products play an
    >important role. A 1degree rise in temperature is a big deal for this
    >business. But the service stations do not have temperature compensation at
    >the pumps.
    >
    >WHEN YOU'RE FILLING UP, DO NOT SQUEEZE THE TRIGGER OF THE NOZZLE TO A FAST
    >MODE. If you look, you will see that the trigger has three (3) stages:
    >low, middle, and high. In slow mode, you should be pumping on low speed,
    >thereby minimizing the vapours that are created, while you are pumping.
    >All hoses at the pump have a vapour return. If you are pumping on the fast
    >rate, some of the liquid that goes to your tank becomes vapour. Those
    >vapours are being sucked up and back into the underground storage tank so
    >you're getting less worth for your money.
    >
    >ONE OF THE MOST IMPORTANT TIPS IS TO FILL UP WHEN YOUR TANK IS HALF FULL.
    >The reason for this is, the more fuel you have in your tank, the less air
    >occupying its empty space. Petrol evaporates faster than you can imagine.
    >Petroleum storage tanks have an internal floating roof. This roof serves
    >as zero clearance between the petrol and the atmosphere, so it minimizes
    >the evaporation.
    >
    >Unlike service stations, here where I work, every truck that we load is
    >temperature compensated, so that every litre is actually the exact amount.
    >
    >ANOTHER REMINDER, IF THERE IS A FUEL TRUCK PUMPING INTO THE STORAGE TANKS,
    >WHEN YOU STOP TO BUY, DO NOT FILL UP - most likely the petrol/diesel is
    >being stirred up as the fuel is being delivered, and you might pick up
    >some of the dirt that normally settles on the bottom.
    >
    >Hope, this will help you get the maximum value for your money.

    If anyone's that bothered about saving cash, I suggest keeping all the little bits of soap left over when the bar has almost run out & squashing them all together to make a big bar again

    There's some proper tight-fisted bastards in this world.

    I wouldn't believe you are getting screwed that bad - not for such a small amount of fuel

    the petrol measuring device is a positive displacement meter - same as you water meter , quite accurate volumetrically - for accurate measurement you really need to be measuring mass flow.

    but a better researched reply can be found at snopes

    snopes.com: Tips on Pumping Gas

    I thought I would also mention something concerning the tip about the throttling of the delivery valve - as you throttle a flowing liquid or gas you can get to a point where large amounts of cavitation can occur because of pressure drop , this would probably convert a lot more of your fuel into vapour than anything else - a lot of research has gone into the valve and seat design of industrial valves to minimise cavitation.

    Save electricity by turning off all the lights in your house and walking around wearing a miner's hat.

    Save on charity donations by spending a pound on clothes at a charity shop, then selling them for 50p to another charity shop. This way you can give twice as much, at half the cost.

    I think.

    If your surname is Toblerone, always take along an empty 'Toblerone' chocolate box when attending interviews for office jobs.

    This would save your potential employer the expense of having to make a name plaque for your desk.

    Hey. I said it was an email, I thought the 'facts' were disputable or rather minimal, and posted it here to see wot others thought.

    Save on washing by turning your pants backward, then inside out then backwards and inside out. 4 days = 1 wash. Or don't wear pants.

    The next door neighbour's car aerial, carefully folded, makes an ideal coat hanger.

    Don't buy expensive 'ribbed' condoms, just buy an ordinary one and slip a handful of frozen peas inside it before you put it on.

    Thats mostly bullshit, tanks underground will not vary that much between -40 and 110+, a root cellar will keep vegs all winter and most are only 1.5 meters under ground, does not matter how full your tank is, the surface area of the gas is fairly constant down to empty, but it will make a difference in the surface area of bare metal and air volume for condensation between day/nite temps at air temp. so the lower you run it the more water it will make. always keep it as full as you can especially in cold weather when it is at it's worst for condensation.

    Save money on jigsaws by taking frozen chips from the freezer and try making a potato.

    I don't think the Japanese lesbians in the condo opposite will let me.

    Make your own inexpensive mints by leaving blobs of toothpaste to dry on a window sill.

    Use striped toothpaste to make humbugs

    Don't waste money on expensive iPods. Simply think of your favourite tune & hum it.

    If you want to "switch tracks", simply think of another song you like & hum that instead.

    Avoid buying a fishing licence by attaching a helium balloon to your line & bait the hook with an acorn.

    Then sit under a tree and "fish" for squirrels.

    Don't forget to throw the squirrels back into the tree at the end of the day.
