How accurate is petrol station pump meter?
Something struck my mind this morning as part of our discussionn in the other thread of best mileage fuel.

First of all, for C200 W204, the manual says that the tank capacity is 60 litres and also it also states on another page that the reserve tank is 6 litres.

So, questions?

1. Do we have 60+6 or 54+6 litres to use?
2. The fuel gauge on the dashboard is referring 66 or 60 litres?

The reason I ask is because, today I fill up my car at Shell, and the pump meter shows that I have pumped in 64 litres !!!! And this is when the distance meter in the car still shows I have fuel to go for another 40 km.

If it is indeed 66 litres in our car, then OK lah.

But if it is 60 litres, that means, oil companies are ripping off users. Pump in 60 litres of fuel but charge 64 litres.

What say you?

Re: How accurate is petrol station pump meter?
mmm.. I have the same problem with my CLK..the reading is not accurate... I try to sangka baik since I used to work in retail O&G before, the meter are all caliberated..

I suspect my CLK reading is not accurate.. I dah malas nak buat kira2 on the SLK as the calculation is in miles and my cikgu ilmu hisab kena transfer sebelum ajar conversion..

should be 60 + 6...

2. The fuel gauge on the dashboard is referring 66 or 60 litres? should be 66 litres...

if true, it's really mind baffling, keep an eye on it during next fill up and re-read the manual...

Re: How accurate is petrol station pump meter?
I never take the fuel gauge on the dashboard as an accurate measuring eqpt but just an indicator with plus minus a few liters error. Furthermore theres no method/procedures to do calibration on this eqpt. So I always take it as an indicator only.

Regarding how accurate the petrol station pump is ... that one susah mau cerita but I once observed a team from the enforcement/ministry do inspection on the pump using a kind of measuring container with glass tube having this measuring *volume* marking. The size look like about 5lit container. They will fill the measuring container and then they counter checked it whether the pumped out volume stated on the pump tallied or not with the volume indicated in the measuring container.

Regarding the car petrol tank ... I always believe it is slightly bigger than the stated volume. Maybe 5% or 10% bigger ... I donno just guessing.

Re: How accurate is petrol station pump meter?
The fuel pumps at the station are calibrated yearly. The calibration date is shown at the top of each pump stall.

This is what happen during the 90's, not sure if it remain the same now.

During calibration the pump is purposely to pump out slightly more volume than the actual reading.
With time, the volume will reduce slightly.
On reaching the the due date for calibration the actual volume pumped out is generally lower than what shown.

The dealer,
Lose during early days of calibration.
Break even at mid way.
Make some toward the end.
Average out ==> break even

We as motorist,
Get more during early days of calibration.
Break even at mid point.
Get less toward the end.
If we fill up at the same station, in theory it average out ==> break even.

To get more we should always fill up at a station with recently calibrated pumps.
But we use more fuel looking for the stations.
Happy hunting.

Re: How accurate is petrol station pump meter?
hi all benzers, here in this thread the owner is talking about his w204...from what i know, there are various older models with fuel tank capacities of 50 litres.

on another matter, am not really sure if there are any same models of the ckd or locally assembled units that have smaller fuel tanks compared to the same model units which are assembled overseas...

on another matter, if what nra21 said is true, the kapchai riders are the ones that gains.., i've always had this feeling that them kapchai bikers are grinning from ear to ear. moreover, i do noticed that they fill up their bikes with ron 97...

Based on nra21 explanation, its the pertol station that is ripping the overall benefit as the chances of one person going to the same petrol station throughout the year is next to impossible.

Hmmmmm good business lah this petrol station then.

with today advance & high technology flow meter ... the accuracy of the station fuel pump can be very accurate up to less than 0.5% error or may be much lower ... even the digital readout at the pump also gave 2 decimal point.. temperature also can effect the density of the fuel ... again this issue about fuel density can be compensated according to surrounding temperature using specialized sensors and computer program ... then to consider the evaporation of fuel when car parked under the hot sun ... etc etc etc ...

i believe with today technology ... the amount of fuel pumped into our car will be the same irrespective which day of the year ... and I also believe if peoples can hacked computers ... then this system can also be hacked ... not mentioning pump operator mixing our fuel with other stuff?? ... I doubt they will do this but anything can happen ...

btw saya bukan petrol station operator ... tapi hanya pesara ... now spending more time at home cleaning & polishing my cars and less driving ... drive cuma bila bini suruh beli garam etc etc kat kedai ... heheheheee ... kalau saya silap mintak maaf ye ..
