Fuel pumps fiddle?

Just Jack

Anyone information on fuel pump calibration. I know think that weighs and measures check and seal them. My question is how do we know if the pumps are legit or not?

How do you know you're getting petrol at all?

Id say buy in large quantities, youll know how many litres fills the tank after a few times.

There's a calibration sticker on the pump, with the date it expires punched out. If it doesn't have the sticker or you don't trust the station contact weights and measures, they can verify if it's legit and verify the pump is calibrated if it it isn't.

I am quite surprised at this from you.
I would have thought that you colm-mcm moderater,with all your (sensible for the most part,I believe) posts on motors would know that the pump nozzle for petrol and diesel are different sizes. or were you just taking the mick?

That's a very condescending post IMHO.

Apologies, Just Jack screwed up the quote tags, I'll edit my post.

You could get a 10L jerry can and fill her up.

50 years ago, I worked with Irish Pump Services. At that time the unit had to be accessed in order to alter the price. I don't think that is the case today. or is it? the reason for my initial post was to enquire if anyone knew this. With prices going up and down. do the stations have to wait for someone to check the seals or can they alter the units by remote?

I think you misunderstood my original post. The point I was making was that any garage short selling fuel will be spotted very quickly, I sorry if you took that the wrong way.

I think your question is very specific, and maybe an email to the NSAI would be in order.

Given that the pumps are electronic, Id say there is less scope for tampering,

All the pumps I see are electronic, so there's no need to break seals to change prices. When they need to change a price the most they'd have to do is connect a computer to it and I'd hazard that most can be changed from the till computer on the fly.

A simple check is get 2 5liter containers and a jug that is measured in mili liters that shows the level upto 1 lite. Purchase 5liters as per pump...empty contents 1liter at a time into secind container on last jug you should still have one liter exactky goin into the second container...anything over under is your diff...

Another way was get 5liters of fuel...mark level in container then empty contents into another container, then go to another garage that you think is legit get same qty, measure...should b 2 lines at same level....

Seem like a lot of work,think I will continue to fill up at the local texaco.
Not the cheapest around,but I think honest.

You got advice and you choose to ignore it, awesome

I seriously doubt that any of the major brands would be underselling. It's easier to just raise the prive by a cent and they're still making the same money. If they were more than a couple of percent out, they'd be caught very quickly.

Id say buy in large quantities, youll know how many litres fills the tank after a few times.

If I did not already know the capacity of my tank, I would refer to the owners manual. Are you implying I'm thick? What has how many liters to fill my car got to do with my original inquiry?

Seriously ? If your tank holds fifty litres and you bring it in on empty, then fill it, if the pump display shows 50 litres you know its right, if it doesn't you know its wrong.

He was giving you sound advice.

So you want to know if it's dispensing the right amount, you don't want to measure a small amount of it (a litre), you don't want to check if the pump shows a higher number of litres for a full tank, you don't want to contact the NSAI, and any advice you do get you criticise.

I've lost interest if I'm honest.

This set the tone for future posts. 'How do you know you're getting petrol at all?

is smart, uncalled for, and not worthy of a mod.

If I did not already know. (which I do) and wanted to know the capacity of my car, I could, and would, consult my owners handbook.

As I have already stated, not worthy of a mod.
I know some people were trying to be helpful, and I thank them.
With special thanks to Del2005 who actually understood the initial query.

My point was that if you are still in doubt after seeing a calibration sticker then you need to satisfy your curiosity by doing a simple test.

To be honest, I think you're out of line and need to lose the MOD element of any poster. A mod is a mod when they post like this. Move on from that aspect and appreciate the advice a member was trying to give you.

Colm was being helpful.

Purchase in large volumes. If you generally fill 60 litres into your tank when the needle hits a certain point and if you have to fill 70 litres from the same needle point then you know you're being done. Very easy, very simplistic and not at all difficult to grasp.

Did you read my original post? If so. please tell me how was Clom been helpful? And I if you sincerely believe that Colms post was in any way helpful. Then I agree "you are done On a regular basis" as in a bit of a mug,

Just for the record, the normal quality of fuel that we dispense to test a pump is calibrated corrected is 20 liters.

The op is just being a knob for the sake of it , dont answer him or her back , dont waste any more time on this thread or person imo ( oh course) :0) !!!!!

Just curious, but what way do you think a mod should answer stupid questions?

I can tell from reading the posts that it wasn't colm who misunderstood your original post and that it was you who misunderstood his answer...

All he was saying is that (without bringing some measuring instrumentation with you to the garage) you can no more tell that the pump is giving out a litre when it says it is than you can tell that it is even pumping whatever fuel type is advertised. It could be water with an artificial smell added to it and you wouldn't know until your car calved a few feet/yards/miles down the road.

what he was saying was that there has to be an element of trust involved - you can hear the liquid coming out, you can see the pump measurements incrementing, but for all you know, it could be water. You just have to trust that the relevant people are doing their jobs and bear in mind that if enough people feel they are getting ripped off, there's something they can do - he even told you what to do.

Unfortunately, while that advice was understood by everyone else, it seemed to be beyond you. The problem was further compounded when, instead of a polite "could you explain what you mean?", you got all aggressive and made yourself look ridiculous.
