A 42 gallon barrel of crude oil yields approx 20 gallons of gasoline and only about 10 gallons of diesel. In the past several decades, the demand for diesel has has grown more, relatively, than the demand for gasoline. It's a supply and demand thing.
That’s not quite accurate, a barrel of crude yields between 11 and 12 gallons of ULS diesel.
The other factor, albeit a small one, is that the Federal tax on diesel is 1/3rd higher on diesel than it is on gasoline.
There is also the seasonal demands which are opposite, people travel more in the summer and so use more gasoline, in the winter diesel is competing with consumption for heating as well as for motor fuel.
