I can understand that the “cleaner” diesel costs more to refine...that makes sense... but the simple fact that it contains more energy, hence should cost more is fishy....
As I mentioned....4-5 years ago it was still making the same energy....right? So why was it almost a buck a gallon cheaper than regular gasoline?
Seems like the second half of your explanation makes much more sense then the first half.
The reports I have read show a very slight reduction in the energy in ULSD (Ultra Low Sulfur Diesel) but almost no difference from the previous.
It cost less before because it cost less to produce. Most Diesel is made through simple distillation of Crude Oil. Most Gasoline takes more processing. Today, additional sulfur treatments are added to the diesel. Also, fewer suppliers of ULSD make the supply and demand curve shift up. We have fewer sources where we can import it from.
