Fresh. Its posible a few of my furl cans got water in em after the easter storms but the caps were sealed although semi submerged in fresh water. Cant see any seperation in fuel when pour in clear container.
Water being heavier than fuel it will be at the bottom of your containers, so why not carefully decant into another container being careful to not agitate it too much.
Just did a test, emptied half a jar Aldi Morello Cherries, top up with
50% pure alcohol. Alcohol floads on top.
You have mixed, stays on top for days.
Not in my case I mixed, next day, just perfect, U don't wont to know how good it tatesssssss.
