Ok Eddie, I take it you're fresh to the Aspen team? Welcome to our happy little gathering here. I think this product has a major flaw. It's not readily available over the counter in many areas. It's too expensive. The empty cans mount up, until I can make a specific trip to the tip to dispose of them. Since my earliest postings on this product, I have bought and tried it. £17 for 5 litres is ridiculously dear, moan about pump fuel going up, but this is dearer still. I have to travel quite some distance specifically to buy it, to an outlet I otherwise would not visit, as it's not on my regular circuit, more expense in time and fuel to get fuel. I washed out the empties and put them in my recycle bin, as it has the symbol for recycling on the can, my collectors removed them and put them back with a note that in future they would not empty the bin if they were in there, not too clever. That means a specific trip to the HWRC to dispose, more time and fuel. Hardly the greenest commodity any more IMO.
Plus side, it does smell nice, if you like that smell, and it's claimed it is better for your health, but I'm always a little cynical about that kind of claim. Better for kit? Maybe it is, hard for me to see that though. So, will I go out of my way to buy Aspen fuel again, simply no...it's simply not a viable alternative for me over pump fuel.
