Morrisons fuel
bought a new to me 2004 Berlingo diesel HDi van.
Hand book - fuel tank 60 liters
first fill - fuel light on to full 48.97 liters (Morrisons Dundee).
second fill - gauge quite low (no fuel light) to full 56.37 liters (Morrisons Aberdeen pump 3).
I owned a Berlingo 1.9 diesel before (60 liter tank) where the bigest fill was 45ish liters.
Ok it's possable to put 56.37 liters into a 60 liter tank, but really?
How trustworthy is a Morrisons fuel pump?

I would imagine that they get at least an annual surprise visit from Trading Standards, who will check the accuracy of the pump deliveries very
carefully, I know when we owned a filling station we never knew when they would turn up. The pumps must deliver amounts of fuel to within very fine
limits, less than 1%, I seem to remember.
They even check the accuracy of our public use tyre inflation machine.

Worked at a petrol station about 35 years ago if memory serves me right I think they are calibrated and sealed units so chances of tampering very
minimal. Like all things mechanical it doesn't mean they cant develop faults, an easy way of checking would be to get a small 5 litre jerry can
and see how much you get for your "5" litres if you see what I mean.

I got 60 litres into a VW Polo with a 40 odd litre tank once.
Shell claimed that some of the capacity doesn't account for the filler pipe - I called bullshit and phoned trading standards. They measured
everything and found no fault - but without admitting liability, Shell gave me my money back (after several months of arguing).
Either - The pump was "maintained" between my complaint and trading standards visiting, the tank was near empty and the pump was measuring
air or I paid for a bike or something before me and the pump wasn't reset.
Choose one of the above that best fits what happened to you!

As mentioned, more likely the fuel light is in accurate, or less likely the sensitivity of the pumps, meaning what clicked as 'full'
wasn't actually full.

They were correct,in a way 
I've had a Fabia VRS,you can massively over fill them as they have a large expansion chamber,which isn't taken into account by the stated
capacity,or by the fuel gauge ; )
If you fill it fully by venting the expansion chamber you can do at least 200 miles before the fuel gauge moves off full,you can get circa £15 worth
of fuel in the chamber at least.
So well done on getting a free fill up!!!!!

Must have been magic petrol then as I didn't get any extra miles out of it!

I regularly put 73 litres in a 70 litre tank on my 'yota.
I have, more often than not, put near enough exactly the tank cap in on refils on other cars. They have reserve capacity.

I had a guy arrive at a pump and fill a can just as I pulled up. He walked off towards the shop and I filled my car. When I got to the counter, they
told me how much and I just told them that that wasn't right, they'd been robbed and only the second delivery was mine. They charged me
for the second delivery only. I presume that they checked the CCTV later to see if they could identify the guy.

Many years ago I filled my car putting in several gallons, when I went to pay the cashier charged me for a couple of gallons despite me telling him it
was wrong. From that
experience it's obvious that pumps can go wrong.
