Here at home I have fuel oil for my furnace to heat the house . I have been haveing trouble with the oil filter jelling up . I asked my oil man to make sure that I am getting #1 miked with #2 or K 1 to help with it from freezing up at the fliter ... well after 2 after hour calls at $ 130 I am still haveing it freez up can I get some type of fuel addtive like they use in the semi trucks use to keep from jelling up?I did ask my furnace man about useing some he has told me that it might work but could not give me a name brand to look for. I am planing to relocate the filter in side the house to maybe get some help I am not to thrilled about that idea got some heat tape but the pakage said not for fuel lines so what else can I do Please help
