Fuel pump accuracy at your service station

The tank is 35L though.

GU reserve tank is only 30L

After adding 32 litres into my 30l reserve tank I stopped filling, never added more than 30 and I really drain it. Surface was level and so was car.
This was at Safeway Cairns and I complained to the operator who basically told me the pumps were accurate and wasn't interested. I kept all the details and contacted the weights and measures equivalent in QLD who said they would audit the pumps.
Three days later they rang me back to advise that the pump was correctly calibrated and they had no explanation for the difference. At least they followed it up, I've never been able to add that much to the reserve tank since.

I did exactly the same thing in Geelong. Same numbers and all. Followed up with a report and got the call to say that it checked right. I have got between 30 & 34lr into my sub many times since.

Next time I full I will stop the pump at 1lt, 10lts & 100lts and take a photo. As long as the final equates then I think the 1lt test must have something to do with the pump or Hose?? It will be interesting to see.

i think the problem is for that test to work you would have to do it every time you fill up, as some pumps might work fine and other not, and maybe the pump will work fine this time and not the next? such a pain in the @rse

According to my manual some reserve tanks are 30 others are 36 depending what motor you have.
All mains are 95 litres

People you need to remember that you can over fill a petrol tank if you keep clicking after it cuts out too many times, what your actually filling is the expansion part of the tank which is meant for when your filled up in summer and the fuel heats up. Within 2 or 4 litters of the listen capacity is normal imo because of this reason but at times when the bowser says i have filled up 10 - 15ltrs more that i would normally put is when i have complained. What i have noticed is that the bowsers that show i have filled more than normal have a fast flow rate but the ones that to me are fairly accurate have a slower fill rate.

Mine was at a slow fill pump that overfilled the 30l sub tank, most servos I use have slow fill.
I did get some satisfaction from knowing that they were inconvenienced by having their bowsers tested, they weren't in the least bit interested. As we were on our trip I kept very accurate fuel figures so took particular notice.

My local I use every week was bang on.. and as for filling amounts I never go by this.. unless the tank was see through and there was a little line I was filling up to.

After reading this thread and seeing other pics/posts on FB when I filled up tonight I checked the bowser at 1L and 10L both times were spot on at the local woolies/caltex servo. Just for 91 unleaded in my commodore.

Filled up two 20lt jerry cans at the Shell in Bathurst and managed to put in 46lts. Said something to the servo they said tough luck, jerry cans are more than 20lt. Went home checked it litre by litre. was 42lt in both. Sent email to shell telling them info and servo did not want anything to do with it and they replied and said they can't do anything and it was up to the servo to sort out. Have not been back and I tell as many people as I can. I was spending between $100 to $200 a week. Happy to give it to someone else.
