Ha! My dad can beat up your dad, and he can get 25L into a 21 litre tank.
Seriously though, the original theme of this thread was some one overfilling at the pump, and then someone else claiming they could get even more in. Because of the filler neck design, it is possible to put a little bit more in, but when you do, it comes out the overflow.
If you are unlucky enough to use a garage that overcharges for its petrol by using short measures, then unless you know how much you should be able to hold, they can get away with it for years. If you have the ability to drain and refill a tank with measured amounts. Why don't you do it and share the results.
Well at least you are consistent - more bollocks!
The original post was about someone running out of fuel and not about overfilling which only became a point after you introduced it. Try to stay with us here eh?
Secondly, you CAN fill the tank to the brim without a drop spilling down the overflow so that statement is also bollocks.
Someone else answered your third bollocks statement about short measures - trading standards measure them regularly
As for measuring the tank, there is no point as the answer will be "more than 21 litres" which was what I said originally and you then tried to make out was a fool for saying say so. I think you will find that a grasp of the facts is always advantageous when attempting to ridicule someone else's point of view. To do otherwise simply makes you look ill informed and rude.
As for filling up the tank and leaving in the sun (not your bollocks this time....), most people I know ride their bike away from the filling station after buying fuel - a couple of miles leaves an air gap as fuel is used.
I must say that you have impressive repertoire - there seems to be an endless stream of things you know fuck all about but are equipped to debate about at length.
The nights must just fly by in your house....
Some advice to consider - when finding oneself in a hole, the first thing to do is to stop digging. I should know better than to argue with an idiot, they always bring me down to their level and then beat me with experience.
I give up - the world is flat after all.
