Petrol measurements/lawnmower fuel

    Today I visited my local Tesco petrol pumps and took two petrol containers labelled as having a 5-liter capacity to fill for my lawnmower.
    They weren't completely empty.

    Here is a link to the receptacles I used
    http://www.buy4now.ie/woodiesdiy/productdetail.aspx?pid=3882&loc=P&catid=102.10.4

    My bill was over 15Euro. The amount of fuel delivered in total was 11.58liters
    and not 10Liters or under.

    Later this evening I will fill my tractor mower with the fuel and once the canister is emptied I will try to fill it with 5 x 1 liter water (using bottled water 1Liter or 2 liter containers and a funnel).
    Any other physical explanation (eg, evaporation) why there would be such a discrepancy.
    At the moment I am hoping that the issue is that the receptacles are 5.8Liters volume rather than the stated 5Liters. Otherwise I think I'll be talking to the weights and measures office or equivalent who watchdog these pumps.

    yes them containers always have more room than 5liters in them, its so when you fill 5 liters its not right up to the cap. i think i once got 6 liters into one before.

    Ok. that's fine.
    I figured that the weights and measures office or equiv. would police the pumps to the nth degree.
    Good so !

    thanks DD

    Correct, the term is ullage, like how your 2L bottle of coke or milk is never to the brim.

    Often you will see a indented mark or line near the top of such containers, and it would be approx 5L to the line.

    What's a liter?

    Do you mean a litre?

    Are you being a little pedantic ? I mean both.
    Out of habit I used the American spelling


    I spend a lot of time interacting with US multinationals and occasionally I've let some of those American variant spellings slip out in e-mails, etc.

    To be honest I'm probably as rigid as you are in this respect most of the time.
    I'd never use the spelling color, for example in place of colour but I have often
    used -ize endings in place of -ise endings and meter, liter , etc.

    it is dangerous to fill petrol cans to the brim, thats why they have the bit of extra space

    "Fuel expands and vapour can build up in hot weather, so avoid filling to the brim"
