Are forecourts mis-advertising pertrol/diesel?

tony.mac139

Has anyone noticed how forecourts advertise pertrol/deisel as .9p, and never round up/down? If I were to buy say 4 litres of deisel at advertised price of 110.9p per litre, where is my .4p change? How are they allowed to do this if decimals of a penny are not 'legal tender'?

Behave yourself.

So if yo go to the sweety shop and you get 2 chews for a penny you would argue you only wanted one for happenny?

No, they are advertised at "2 for a penny" not "halfpenny each"

Dont get me wrong, iam not trying to scrimp on a couple of pence, but the garages are gaining a few pence on every customer, it will soon add up.....my argument is more of a principle

How much are you charged for your 4 liters? 443p 443.6p or 444p

If you got 6 liters would it be 665p 665.4p or 666p?

Brain is not functioning well this morning and there is an old thread on here somewhere that explains it better but here goes.

The amount of fuel you actually receive will vary with temperature anyway. So if you buy in the winter you will get a bit more than in the summer as will buying in the morning as opposed to later in the day. I'm not sure at what temperature pumps will be calibrated at.

To see the effect of temperature on volume just look at a thermometer. The mass of the fluid is constant but the volume changes quite dramatically.

Taking temp out of the debate you will never be buying say 4l it will always be a shade more. What you want to do is asy put 10l in the car and on your example it will cost you £11.09.

If you stick to your example and buy +/- 4l and the cost is £4.44 then you will have received 4.0036l (give or take what their error allowance can be)

No they're not. You will never be able to discharge an amount out of the pump that would end up as a fraction of a penny. The pumps are set to discharge in integer monetary amounts and the litre display is there for informational purposes.

Sometimes I check my receipts and when I calculate the price per litre multiplied by the litres pumped into the car there will be rounding up and down. So £26.993 will be charged as £26.99 and £26.998 will be charged at £27.00.

Thanks all for clearing this up, maybe we are not getting "ripped off" but still think it would be easier to just charge 111 instead of these silly .9's in an attempt to make it look cheaper.
however in reply to your suggestion of getting a job conner, i have a very good one thankyou, which has fortunatly left me debt and mortgage free at the age of 32, thanks for your concern tho, regards.
