    Was talking to a friend yesterday and he said he has a friend who so cheap that he only fills the car literally just after he wakes up like before sunrise, i laughed at this and said why and apparently cuz the temperature of the petrol has been cold all night long that when you fill colder temperature over more hotter then you save money. i was laughing at this at first but apparently he is saving money, lol.

    anyone heard of this before? lol

    p.s. - by the way im not trolling, apparently this is what this guys does lol

    Read this: Buying cold gasoline
    Summary:
    Whilst temperature does have a very measurable effect on the volume of gas you get, filling up in a morning when the temperature is cold, as opposed to in the middle of a hot afternoon has no practical effect on the volume of gas you're actually getting because, in all but extreme cases, the temperature the gas will be dispenses is not related to the current outside conditions.
    The temperature that the gas is dispensed is based on things outside of your control (and most likely your ability to exploit).

    Guilty as charged :Fear: but I do it to get rid of the excess petrol that pours out so it doesn't spill everywhere :cleaning:

    But I remember back in the days you would see literally every man and women in the forecourt violently shaking the nozzle to get every last ounce of leftover petrol into their tank, my old man used to have the attitude of every drip counts! :spit:

    I don't know much about anything to be honest, but I did manage an esso petrol station in the eighties. As far as I can remember when the tanker dropped its 9500 odd gallons six foot ish underground I assume the temp would be pretty constant all year long.
    I passed my test in 76 but my first car in 75 while still at school ( naughty boy ) a triumph herald convertible for £15 ! I think petrol then was about 68p A GALLON !
    When you've finished pumping petrol you only get the drips in the gun nozzle, NOT the several litres in the long hose.

    I haven't been driving that long, coming up to 9 years, it was actually roughly the same price it is now when I passed. But "back in those days" referring to my post was in the 90's when I was a kid, it was like 70-80p from memory and leaded 4 star petrol was still around!

    There must be something in it as the teams at the IOM TT chill the petrol before putting in in ot the bikes tank so as to get as much possible in there. How much extra I suppose is debatable, but when pushing for the max needs must try everything :Smile:

    Can't remember who all were from - - who remembers the tiger tails (esso) and no I'm not old enough to mean Pratt's. Also little white busts of our world cup squad 1970 ? A green cut out board for silver coins of the history of cars and my favourite - - fake James bond style bullet holes stickers I stuck all over dads hillman minx much to his annoyance !

    I think the chilled fuel is to do with density and how the fuel burns better when cold ie with intercoolers etc, but im sure in a minute way the vapour will exband with heat.

    last night went to local BP who run cheaper fuel deals for 2 days a week and was shocked to see them selling for 98.7p while ASDA is 99.7p.
