winter time to assist in fuel gelling.
dont need any assistance to gel fuel
around here we have a large refinery, shell oil, and they just sunk a stink pot full of money expanding it. we have a few smaller ones, valero and clark oil. amoco here just tore down in the last couple years about 50 to 100 tanks. dont know the reasoning behind it especially since there hasnt been a refinery built in the us since the early/mid 70's. perhaps to keep prices up with no supply but an increased or steady demand? nah.... they wouldnt do that
