When I opened up my brand new gallon of byrons rtr 20% fuel, a very small piece of the seal which is foil and plastic fell in my fuel. I'm not sure if I want to dump almost a gallon of fuel into another jug for this small piece of seal. I know its in there and I know I'll be careful filling my fuel bottles but is there any danger with leaving it in there until I use more and then dump it into another gallon? I'm also kinda clumsy so I know I'll spill some with it being almost full. As always thanks in advance, Steve.
