Skerford, Be careful who you are giving or selling the oil to, If you are passing on gas oil to someone with a condenser boiler it will destroy their heating system and cost them dearly, If it kerosene it would be ok, I had to drain my tank recently and it was more hassle than it was worth, It seemed to take a lifetime to fill the 25 litre containers and I was lucky that I have a friend who works in that game to sort it out for me. It was gas oil and he took it away to give to his father for use on farm machinery, Other wise he told me it would cost me to have it taken away.
