Evaporating Fuel / Aspen

In addition, if your dealers sell a container advertised as 5litres but containing 4.5litres at the point of sale, surely this is an offence under under the U.K weights and measures act?

Not true.....the size and weights on packaging in the UK are 'at the time of manufacture and packing' which is designed to take into account variables such as evaporation- as in this case.

Can you think of any other examples were the weight or volume reduces so much?

Seriously, I buy 5 litres of Aspen I expect 5 litres not 4.5litres.

What is the accepted variance from the marked amount at the point of sale?

I find 10% or 2.80 euros quite unacceptable.

We are all well used to buying cereal whose boxes are two thirds full but these are sold by weight not volume.

 I do not think consumers would accept short measures anywhere else at the point of sale without the seller offering a pro-rata reduction.

Agreed, but Aspen for example comes under 'packaged goods' law, which volume is determined at manufacture and packing, whereas fuel purchased from a filling station isn't, so 5 litres dispensed, has to be 5 litres.....no variables.

[Ty Korrigan]

Right, I believe goods can be sold over weight but not underweight.

If the goods are sold underweight due to poor storage, packaging or time between manufacture and eventual sale then surely this is an offence unless advertised?

It is quite one thing to sell 5 litres of Aspen and the client experience evaporation of the product but quite another to sell it under volume in the begining.

Do you have any links to the U.K 'packaged goods' law?

 I'd have thought there must be a reasonable allowance outlined within it for fuels?

As an aside, when you state there is only 4.5 litres in a can of Aspen, are you judging that by the clear measuring strip on the side of the can?

 

You do get containers apparently showing less that 5 litres, but this is because the plastic cans bloat outwards causing the level to drop.

 

Once decanted into a more robust container, you normally find there is actually the correct quantity......or at least very near. Certainly not 500ml less.

 

A manufacturer should take into account any loss of weight or volume from time of manufacture and packaging to time of sale (called desiccated goods)....therefore, Aspen in this example should effectively 'overfill' to offset any evaporative loss, although, I suspect they will blame the retailers storage conditions rather than their own measurements. However, like others on here have already mentioned I have never lost the quantity you mention you have to evaporation.

If you got a 5 litre pre mixed can with only 4.5 litres in it would that in effect mean that the oil to fuel ration had increased ( assuming its only the fuel evaporating and not the oil as well  )

No, I regularly decant into an empty and unbloated Stihl container with grades.

Yesterday, in the store, we weighed several Aspen containers on kitchen scales then the dealer opened a container and measured it with a graded jug and found it was 500ml short.

I should film an opening and measuring into a glass measuring jug...
