Filled Up with Sainburys LPG last night.
« on: 27 June 2019, 17:59:48 »

Then went to pay for it and asked the Cashier if He could explain to me how I managed to get 57 litres of LPG into a 45 Litre Tank that will normally only hold about 37 litres brimed even when competently empty.  >:(

He just gave me a blank look and mumbled something about sometimes stuff happens.

Not to me it doesnt, was my replky, never mind, here's my name and number get a Manager to call me urgently tomorrow (today)

Still waiting.  :(

I would be tempted Zirk to get in touch with the local Trading Standards Department and get them to investigate with checks done on Sainsbury's equipment.

How many more motorists may have been over charged?!  :(

No, all the Zero's before filling.

Someone did say to me a few years back that when you connect the Nozzle Pump to the Car, if they take a while to reset the Pump and or Activate it ready for fill that during the idle time your tank presure will slowly fill the Pumps Hose up, cant see it myself, even if it did in thoery you would get it back when youve finished filling. I mean end of the day this is Sainsburys not some back yard LPG outfit.  :-\

There's no way you'd get 20 litres into the hose (and your LPG tank has a non return valve in the filler anyway).

If those 20 litres had existed and wouldn't fit in the tank you'd know about it by now. ;D

Might be worth checking your filler valve is still cutting off at 80% fill. If it is, you've been done, IMHO. >:(

I know if I was filling with petrol and that happened, I would want something done there and then... Can't see a manager ringing you, put it on Twitter and Facebook, Sainsbury soon contact you.

My thoughts exactly, strangly, on the way back the Contents gauge was reading empty ??? but this morning went straight back up to full as per norm.

Ive managed to speak to the Manager tonight, he did say he put the Pump OOS pending an Engineers visit, He was quiet under standing with what I informed Him and agreed something wasnt right. I explained that I keep a good record of my Fill Ups, my MPG and what to expect in miles from each Tank fill up, which I do and I can prove, He's response was understanding and asked me to pop in again, I replied I would run the tank empty and see what the Miles and MPG figures are ( you never know) but either way we both agreed I was probably due some money back.

Quite a pleasant Phone Call if Im honest, could have easerly gone the other way.

Iirc LPG pumps aren't subject to weights & measures regs, due to it being sold by volume - or something like that ?

Dont know, but either way I would have thought they would need to be Calibrated for Retail Delivery somehow.

Have to agree, now they've got your money, you've got a hard time to get their attention. Not to mention that the 'manager' who calls you (if they ever do - I personally doubt they will) won't be able to conceptualise that you can only fit 37L in a 45L tank and that you can't overfill them like you can with petrol tanks (a couple of litres into the filler hose I mean).

If you paid on credit card, I'd charge it back, should get you their attention, or some free fuel...

ive done about 80 miles since filling up and the Petrol / lpg guage is still reading a full tank.

Never done that  before after 80 would normally read around 3/4 full. Hmmm.  :-\

I think it doesn't have to be legally calibrated in the same way as a petrol pump (which is subject to weights and measures).  Hence you do get inconsistencies.

But if its clearly way out, that's for trading standards I reckon...   ...although in this case, they have done the right thing and taken the pump out until its checked, so top marks to them :)

Well this is London dont forget, trying to get the Police out for a Serious Crime is near impossible let alone a potential miss reading Petrol Pump, would have been in for long wasted wait. If I had driven off and refused to pay then I probably would have got a Knock on the Door at some point and it certainly wouldnt have gone in my favor.

I had a couple of Chats with them now and its already on the Cards that I will get something Back and potentially a In Store Bonus Voucher or Something.  :)

For future reference with Sainsburys, as Ive now found out, the Peeps to talk to are the Customer Experience Managers, there the ones that listen and get things moving.  :y

Wel lIm 150 miles in now and its still showing Full Tank on the Gauge.  :o

What do you reckon if it did overfill, problem at my end or there Pump.

I was under the impression its regulated on presure at the Pump and therefore should cut off around the 80% full mark.  :-\

It's not a Police issue. You should get local Trading Standards involved, as it's their responsibility. And they take poorly calibrated equipment in petrol stations very seriously. After all, if they can't measure it correctly, how can you be taxed correctly? :)

No idea LD, its a 2005 Corsa 1.2 Dual Fuel, yea I know you hate them but its the later Injection type, runs really well if Im honest. I,ll try and have look tomorrow, Donut Tank.

Ive a funny suspession it also slapped the full amount in as well, as a 150 miles would normally be showing half a Tank by now

Trading Standards would or could be an option, if, Sainburys didnt play ball, but in all fairness, although a bit slow to pick up on it, they do seem to be on the case, no doubt the full story and the outcome will reveal its self in a few days time.  ;)

So outcome is the Pump did over fill my Tank, the normal MPG I got and the extra Range I got now proves this, I have filled up twice (brimed) at other Garages and Im getting the normal Fills, around 37 litres to Fill, around 80% of Tank Capacity, so I can confirm it was a Pump issue and not my end.

Im surprised it didnt piss out or Vent wben it overfilled me, but the word alarming springs to mind.

Surely the lpg liquifies as it is put under pressure in the tank, and  as the capacity of the tank is measured in litres which in this case is 45 litres  how could you possibly fit 57 litres in there as you cannot compress liquid?? Or am I missing something here?  Of course I believe what happened to you..  I got 100 litres in my senators 100 litre tank once!

With your latest post I assume now Sainsbury's are going to do something for you? Believe me no retailer relishes an encounter with Trading Standards, so no doubt as it is such a leading company as Sainsbury's they will do more than give you the due refund ;)

I do wonder though how many other motorists who have filled up at this pump were also over charged ::) :o

Yea I was thinking along them lines as well, posibility if the Stations Main Storage Tank had just been filled before hand by the Tanker, then in theory the Liquid is cooler, but everyone keeps telling that Full tank and a near empty Tank of LPG should be at the same temperature, still not convinced at that one though.  :-\

This will probably explain if anyone can understand it   I dont :y

             
The molar volume of a gas expresses the volume occupied by 1 mole of that respective gas under certain temperature and pressure conditions.
The most common example is the molar volume of a gas at STP (Standard Temperature and Pressure), which is equal to 22.4 L for 1 mole of any ideal gas at a temperature equal to 273.15 K and a pressure equal to 1.00 atm.
So, if you are given these values for temperature and pressure, the volume occupied by any number of moles of an ideal gas can be easily derived from knowing that 1 mole occupies 22.4 L.
V

For 2 moles of a gas at STP the volume will be

As I said in reply   #1 ::) ::) :D ;)
I wanted to ensure I that I had my facts right Lizzie before rattling cages, ie, has the Pump done my out of a few quid or has it actually over delivered, which should become apparent on my next Fill this week.  :-\

Trading Standards would or could be an option, if, Sainburys didnt play ball, but in all fairness, although a bit slow to pick up on it, they do seem to be on the case, no doubt the full story and the outcome will reveal its self in a few days time.  ;)

 :y :y

With your latest post I assume now Sainsbury's are going to do something for you? Believe me no retailer relishes an encounter with Trading Standards, so no doubt as it is such a leading company as Sainsbury's they will do more than give you the due refund ;)

I do wonder though how many other motorists who have filled up at this pump were also over charged ::) :o
No, it was over filled Lizzie.

But you paid for gas you did not get to keep? ???

You paid for 57 litres, when you could not have possibly filled up with that? :o

In my book you should only pay for what you actually recieve, can use.   ;)

But he was not able to use 57 litres, although he paid for them. Like paying for 2 pints of beer, but only being able to drink a pint and a half. ;)

And that was now proved to be down to a faulty pump.

Well, I am totally confused now!

What is the problem then if Zirk paid and used 57 litres?

His opening post, and others following, have been saying something different ::) ::)

Mind you I have never used LPG, so know nothing about it :D ;)

A 60 litre tank which is most prob what you have...filled to 80% will be 48 litres plus or minus maybe a litre for temperature. Some stations keep filling more than others IE above the 80% which is normal, thereís also the possibility that the float in the tank did not work properly however itís been said that itís done more miles than normal on a tankful so it must have been in there. Iíve filled a Senator 100 litre tank to 100 litre and it was in there!! I was not paying attention at the time as we expect the pump to do it for us. Itís just an anomaly he got what he paid for.

ok just to clarify, my original post was based on the fact that I was p'd off because I was charged for 57 litres which had aperently got pumped into a 45 litre Tank. In my mind no way.

But having done a couple more refills I can confirm that around that amonut was delivered, or there abouts, I normally do around 300 miles on a 37 / 38 litre fill up, works out about 37 to 38 mpg poodling around, so what I actually did was when I got  close to the 300 miles, from the original Fill, I brimed it again and could only get about 16 litres in there, so by adding the 2 fills together and the 2 Milage I got and then dividing them by 2 got me back to where I normaly am, if all that makes sense. ;)

Simple question: Is the 45l an absolute physical capacity or a nominal capacity with some 'breathing' space left in the tank? When I was looking at LPG systems iirc they quoted the physical capacity of the tank & a second smaller normal fill capacity.

Itís always absolute,  but filled to the so called mandatory 80% so of course a 100ltr tank should only be filled to 80ltrs.

Bearing in mind because of the pressures involved, you can get more in to the same area, which is why the valve on the tank should stop the flow when (80%) full.  Clearly that failed this time, be it due to a fault in the tank valve, or a fault with the pump - I guess given enough pressure from the pump, it could overcome the tank valve  :-\

If you look on the tank I bet it will say somewhere 60ltrs. Thatís why there is 47 or 48ltr fill capacity recommended as that is 80% if the total space which is considered safe.

Its more than that. If you increase the pressure, it will become more liquid, and some liquids can be compressed more (by additional pressure).

Obviously, the more you put in above somewhere in the region of 80-90%, the pressure will increase dramatically.

I'm not sure you have.  ;)The liquid lpg is not significantly compressible and the pressure is pretty much unrelated to the fill level. It sits at the vapour  pressure of the propane at whatever temperature it's at. Pretty much like the boiler on a steam train, it behaves the same regardless of the fill level. As the liquid takes up space the vapour condenses to equaluse the pressure. The 80% limit is there to accommodate expansion as the liquid warms up, because if there isn't room for the liquid you do have a problem. :o

Not sure you did when you repeated the Physics lab experiment of filling a tin with gas from the unlit bunsen burner, put the lid back on which has a small hole in it & ignite, but you were only meant to blow the bloody lid off, not the doors, roof & walls. :-[ :-[ :-[ :-X :-X :-X
