Fuel/oil is lighter than water. Thats why we get oil slicks in the seas after a tanker disaster. It doesnt sink to the bottom.

 

...and more relevantly, that why your machines wont start if you leave fuel in them over wainter as the hygroscopic nature of ethannol draws moisture fromthe atmosphere and forms as water in the BOTTOM (being heavier than the fuel) of the tank, so the first thing your fuel pick up is going to draw on to start is water.

I always recall petrol as being 0.73 where water is 1. I'm sure it's slightly different with some 2 stroke oil in there but it's still surprisingly light.

I'll have to go back to keeping petrol in an old metal oil can. I've recently bought some Duckhams classic 20W50 which is in a metal can so they are about.

Didn't relalize a sealed  plastic container was that permable?

 

Is this only for aspen as Iv'e not noticed with regular petrol or 2 stroke?

Reading this I am surprised that a dealer would have stock from a year ago still on the shelf - whether the dealer had it in their store or the wholesaler had it in theirs - sounds like tying money up for nothing keeping that much stock?

 

For the OP, all my other machines use the same fuel (OK petrol in my case), mowers, saw, hedge trimmers, and so on, so it all gets used up reasonably quickly (the mowers work OK with 2 stroke mix, and all the others need it, I just use the same) - might be something to consider

 

Yes, be interesting to see the differences between fuels and cans see what makes a difference

Errrr.....I wouldn't

Aspen 2 weighs 0.69 kg per litre.

I'll Google translate their info on evaporation.

The 5 litre are the worst size for evaporation a 500ml per year.
