-I am still at a total loss as to why diesel is so high. Here in the Northeast fuel oil has been the dominant heating source for decades, and until fairly recently diesel was always cheaper than gas, summer or winter. Now it is almost a dollar more per gallon (heating oil is up in this range, too, and there are no highway taxes on that). It has to be cheaper to refine diesel or heating oil than gas. In recent decades the cost of refining gas has gone up substantially, with first switching to no-lead, then such things as winter (ethanol) blends, MTBE, etc. Incidentally here in the northeast in recent years diesel is higher than gas summer or winter. In theory gas comes down in spring when they switch off winter blend, but not recently (maybe the price increases slow down for a week or two).
