Getting the Most out of Petrol

[LS1Chubby]

Hi all

Got sent this in an email, wanted to get everyones opinion on it.

ONLY BUY OR FILL UP YOUR CAR 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.

to me this has some logic to it.

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.

Sort of agree, i wonder how much difference it would make if any.

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.

Meh.

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.

Agree with this point.

Fuel isnt a huge issue for me, PULP prices are always high so it makes buckleys if i fill up mon, tues, wed etc. Plus my car isnt a daily anymore, got a honda civic to run around in. Do these claims ring any truth? They make sense except the handle holding point and half tank bizzo, what are your views? All BS?

You do realise that these tanks are 5-10m underground at a minimum and that temperature that deep will barely fluctuate if at all. That deep the ground temperature stays at a constant in line with the average atmospheric temperatures. Not to mention they're buried under concrete which is a poor conductor.

As for fuel evaporating, the only time you lose it when it evaporates is when you open the fuel cap, so again another thing that won't save you fuel, if anything you may lose some topping it up frequently.

No im not familiar with petrol storage hence the thread.

lol @ saving on petrol vapours. You'd probably waste more going slowly, allowing more vapour to escape than pumping it in faster.

They all make sense. and are perfectly logical, but i highly doubt the amount of fuel you would save would be very much, if at all.
The inconvenience of doing all that would out way the benefit unless you lived a very boring life. For me, i need petrol, i cant drive without it, i need to drive, so i buy petrol its a vicous cycle really lol.
If your really that tight with petrol, either work an extra hour a week, or pussy foot more often, heck even turn your car off and roll into your driveway if you feel its necasary.

Agreed mate. I dont understand why people would go to these measures.

There is one trick that I always do, once the bowser clicks off and your done, dont let go of the lever handle, keep it held open and grab the hose and lift it up so the remaining fuel left in the hose runs into your tank! I was told this does nothing from the lady inside the petrol store, but I have tryed doing that with the nozzle outside my car and the fuel in the hose comes out. Your paying for fuel and its going to the next person who fills up.

I always do that, not to save fuel, just so I make sure I don't drip fuel over my paintwork lol.

That's the only suggestion in here though that would really give you any fuel. The rest are just complete speculation.

Surprised Current Affair haven't done a beat up story on it claiming massive savings to be had for all......

I do that, when you think about it that line must hold what 250ml? So for the first 250ml or so the previous person has paid for it because its sitting in the line, then you fill up, then lift the hose up, your just putting fuel in that you've paid for + 250ml for free! hey, its probably equal to the 4c vouchers lol

On that note, so many people DONT do it, I also get a stare or two like "wtf is this guy doing??" and im like "yeah bitch, none of you's are getting my fuel...gigidy"

Not this again!!! When will people learn? I see that on a forum or via amail at least once a month...
