Expect to pay considerably more in the coming months.The strategic petroleum reserve has been drawn down to cover the loss of heavy sour crude oil in world markets ..ie the ongoing wars and hard to see how it will be replenished.Heavy sour crude is used for making diesel fuel,jet fuel and kerosene which is mostly imported and refined here.The US pumps and refines light sweet crude used in making gasoline and the excess is exported.Our refineries are not configured/able to distill light sweet crude to make diesel fuel.Most of our heavy sour crude comes from Canada,Venezuela,Gulf Of Mexico and the Middle East.Middle East sour crude no longer available to the US and what does get out goes to far east markets.
