Sounds like the plant business - Are they buying blue flowers or red ones, so which do we grow.

Dumb question,
This is the widest spread between diesel and gasoline that I have ever witnessed on a retail level. Usually reg and diesel are close, with diesel usually higher, but a rough avereage is diesel being $.30 lower.
With your example above they move faster than I would have thought between the two. What is going on with gas?

They move faster on an individual refinery basis, but there are lots of refineries in the system. So the overall effect on national inventories can be a lot more sluggish.

Diesel prices rocketed up the past few years as Europe began consuming more of their own diesel and exporting the gasoline. That's why diesel prices ultimately went higher than gasoline. But gasoline demand has recently been rising strongly, and the price has shot up to compensate.
