Since there are few passenger vehicles (not including pickups) in the U.S. that run on diesel, diesel doesn't have the same price cycle as gasoline. The cycle of diesel prices is that they would be at their lowest in the summer, start to increase in the autumn (due to the fall harvest and then when people fuel their oil tanks at home), peak at the winter because of home heating oil being at it's highest demand, and then decrease after spring planting.
I've owned a diesel VW for the past three plus years and this has pretty much been my experience. With fuel prices increasing at a ridiculous rate for the past year, diesel prices should level off over the summer, but come winter they should go even higher than they are now and become really painful.
