PopG, I had a conversation with my supplier to see if the refinery or supplier put anything in the oil before it gets to me. NO was the answer. He also didn't recommend a biocide, in fact he was totally against it.
I had the same discussion with my supplier, but with a different outcome. I get ultra low sulphur heating oil, and add biocide, lubricity and cold flow additives to make it suitable for my common rail diesels that require the lubricity. The other additives might not be necessary, but they cause no harm other than cost, but I can be assured of the quality of my fuel. I do not use it for heating oil at all.
