Charged Wrong Price For Petrol!!

fusty

I have just put some Petrol in my car at my local supermarket petrol station.
As you get points per litre (not £s) i put 10 litres in @ 106.9/litre.
This should come to £10.69, but the pump said £10.70!!
I pointed this out to the pump attendant who was taken aback by this & said he hadn't realised this as he never took much notice, but said he would raise it with the manager.

This petrol station has 12 pumps so although it is only 1p per 10 litres how much extra profit are they making?

Next time you 'fill up' check the price !!

Are you sure it wasn't 10.01+ litres?

goldspanners

so you can be charged 0.01 pence now?

anewman

If 1 litre = 119p, 0.01 = 1.19p so unfortunately with current prices, the slightest amount costs a penny. But the pump *should* display a value of litres and a price that add up, definitely agree.

Assuming the supermarket is fair (ha!) and they obey mathematical conventions...

If you were to fill up with 10.0049 litres of petrol, this would be rounded down to 10.00 litres and would be displayed as such on the pump.

However, 10.0049 * 106.9 is 1069.52p, which is rounded *up* to £10.70 on a 4 sig. fig. pump display.

This is dependent on the pumps being accurate enough to measure this, of course. But in theory it is possible.

its like asking, if i put in exactly 1 litre of petrol how can they charge me 106.9 p.

Not quite, Goldspanners.

More like... "If I put in exactly 10 litres, why do you not charge me £10.69?"

Id have to agree with cardelia. Because of rounding innacuracies your price will be slightly off. you probably got the fuel you paid for. Coincidentally, I work in a supermarket petrol station which charges @ 106.9 per litre (providing you mean diesel) so im going to try n find out from my manager if this happens in my neck of the woods.

You didn't get 10 litres, you got £10.70 worth of fuel which is slightly over 10 litres = 10.009 litres to be exact, but pumps won't be this accurate.

Exactly, if you want to spend only a fixed amount go by the money counters not the fuel in litres ones-much more accurate that way.

Unless of course the filling station has very high tech pumps which allow the customer to preset the exact amount of fuel via a metered delivery, in which case you should only pay the price advertised.
