Oil Delivery - Possible to pump 320 litres in 1 Min 9 Sec from Oil Delivery truck?

vicwatson

Hope this is the correct forum for this question, Mods please move if not tks.

Had oil delivery in March (300 litres) and marked a clean stick with the height in the tank

Had oil delivery today (320 litres) and the delivery line was about 2 inches below that line I had marked for 300 litres in March

I smell a rat. But how can I prove that I'm not getting what I'm paying for ??

I got a receipt but this looks like a modern print out and not the old ones I used to get that looked like old digits on it. This looks like a print out just.

The time of pumping start to finish is on the receipt and it seems it took 1 minute 9 seconds to pump 320 litres - is this possible? Are all pumps on oil delivery trucks different - I'm guessing they are, the truck was a 12 D so fairly new.

Any help would be appreciated. Hate to think I'm being screwed.

hmmmm.....seems tome that marking a line like that means exactly nothing unless you start with a completely empty tank.
If there was more in before your last fill than there was this time it's perfectly plausible the lines dont match.

Was the tank empty on both occasions? If it was, then contact the oil company with your worries. They will not want to be making mistakes either and will be glad of your call. Don't go jumping down anyone's neck, just calmly explain your worries. This is assuming that you answered yes to my first line.

320 litres in a little over a minute is fast, but probably not impossible.

500l/min from a little portable pump

It comes with 2" BSP inlet and outlet ports and is capable of transferring diesel, gas oil, red diesel or biodiesel (30% biodiesel content) at up to 500 litres per minute.

also, as an afterthought? does oil expand / contract much with temperature? Mind 2 inches is a lot over the size of a tank.

Could be the driver is scamming both you and the company.

If you wanted to play it subtle you could always ring the office and ask them for a copy of the invoice and see if it matches what the driver gave you? My driver always prints the receipt from the computer attached to the truck, there'd be no way to scam unless he recalibrated the pump every day.

Have no plans to jump down people's neck just trying to work it out in my head really .

I really cannot remember if the tank was empty/close to empty in March so....

It was almost empty today, so I've marked a line of 320 litres on my dipstick, when I next need oil I'll get 320 litres also and let it run down to near empty again and then I can compare.

Thanks for your help on all responses.

As I say the receipt is like a print out (not the the older ones I used to get that had a mechanical looking figure on it) Maybe newer trucks have newer machines and dont use this type of font anymore ?

The newer trucks have meters that are connected to a computer and printer in the cab.

I have an oil transfer pump that does 60 litres per minute. I remember talking to a delivery driver but I cannot remember how fast the lorries are but I remember thinking, jaysus that's fast towards mine.
I think it was in the region of 350 - 450 litres per minute depending on the unit.

I just topped up with €500 and i imagine it took less than 2 minutes.

Stand and count to 70 and see how long that feels.

But this was 69 seconds :D

I know what you're saying.

Cheers for all replies, will keep an eye on the next 320 litres.
