Wondering if anyone can help with this, I have oil central heating and am wondering is there any way of telling whether you have gotten the amount of oil you are paying for? The reason I am asking is because a neighbour of mine suggested that he gets his oil at half price because he knows a couple of "rogues" who leave people short? He has told me he will get me a fill also, but alas I have a conscience and cannot do it knowing I may well be stealing from others who have paid. I know they have a clocking card on the tank, and they clock it at zero and again when the tank is full, but does it work accurately, how do you know. The last tank full I got was 20euro cheaper than everywhere else and from a different supplier than I usually get, but seems to have run out far quicker than usual, possible paranoia or maybe not!!
